How to Choose the Right Backpack for Scouting Trips: Fit, Sizing & Packing Tips”

Finding the right backpack can make all the difference on a Scouting trip.
The right pack helps you carry your gear comfortably, keeps things organized, and lets you focus on the adventure instead of sore shoulders. Whether you’re heading out for a weekend campout or a longer trek, knowing what to look for in a backpack is a skill every Scout can master.

We’ll break down the most important features, explain how to measure for the right fit, and share practical tips so you can hit the trail with confidence.
In this article, you’ll learn how to choose a backpack that fits your body, matches your trip length, and keeps you safe and comfortable.

Understanding Backpack Types and Sizing

Choosing a backpack that matches your trip’s demands is one of the most important gear decisions you’ll make. A pack that’s the right size for your gear and trip length keeps you comfortable, prepared, and focused on the trail. A pack that’s too small forces you to leave out key gear, while one that’s too big adds unnecessary weight.

According to REI’s expert guidance, most backpacking packs start at about 45 liters and can range up to 80 liters. For Scouts, the volume recommendations break down clearly by trip duration:

Day packs are your go-to for short outings where you only need water, snacks, a first aid kit, and maybe a rain jacket. These lightweight packs typically feature simple designs without complex suspension systems, making them perfect for troop meetings that include short hikes or day camps.

Multiday packs step up the game with better organization and load-carrying features. These packs include multiple compartments, external attachment points, and more robust suspension systems to handle the extra weight of sleeping bags, cooking gear, and extra clothing. The Scout Society notes that backpacking packs are inherently heavier than day packs due to these additional features.

Extended packs are built for serious adventures like Philmont or Northern Tier expeditions. These packs can handle heavy loads and include features like removable top lids, compression straps, and reinforced high-wear areas. However, Backpacking Light forums recommend that Scouts never carry more than 25% of their body weight total.

Before getting into the technical details, take a look at this clear, step-by-step video on choosing the right backpack type and size for your trip:

Choosing the right backpack depends on your trip style, length, and the gear you plan to bring. Select a pack with the right volume for most trips (often 50 to 65 liters) and adjustable features for comfort. Knowing your gear first helps avoid buying the wrong pack, making your backpacking experience more enjoyable and efficient.

Key Considerations for Scouts

Choose your pack based on the longest trips you’ll realistically take.
If you’re planning to attend high adventure bases or go on extended backpacking trips, invest in a larger pack that can handle those adventures. You can always pack less in a bigger pack, but you can’t fit more gear in a pack that’s too small.

However, don’t sacrifice essential safety gear just to fit everything in a smaller pack.
Efficient packing can sometimes allow you to use a smaller pack than the volume charts suggest. Rolling clothes instead of folding, using compression sacks, and choosing multi-use items can significantly reduce the space your gear requires.

Always check if your troop or council has recommended brands or models before making a purchase. Many Scout shops offer discounts, and your leaders may have experience with specific packs that work well for your area’s typical activities. Some troops even have loaner gear programs that let you try different pack sizes before committing to a purchase.

The relationship between your actions and results applies directly to gear selection. If you consistently struggle with an uncomfortable pack or run out of space, the input (your pack choice) needs to change to get better outputs (comfortable, successful trips). Focus on using the right tools for the job rather than struggling with inadequate gear.

Getting the Right Fit: Torso and Waist Measurements

A backpack that fits well will feel lighter and prevent injury. Proper fit depends on two main measurements that work together to distribute weight correctly across your body. The most common mistake Scouts make is choosing a pack based on height or general size rather than these specific measurements.

Torso length determines your pack size. Measure from the C7 vertebra (the prominent bump at the base of your neck when you tilt your head forward) down to the top of your hip bones, also called the iliac crest. Have a friend help you with this measurement using a soft measuring tape. This distance typically ranges from 15-22 inches for most people, and it’s the primary factor that determines whether you need a small, medium, or large pack frame.

The hip belt measurement is equally important because it handles the heavy lifting. The hip belt should sit comfortably on your iliac crest (the bony ridge at the top of your hip bones) and transfer 80% of the pack’s weight from your shoulders to your hips. Measure around your hips at the bony ridge. A properly fitted hip belt will feel snug but not restrictive, and you should be able to breathe normally.

Fitting Tips for Scouts

For younger Scouts, focus on torso length rather than height or leg length when selecting a pack. A Scout who is 5’8″ might have the same torso length as someone who is 5’4″ if they have longer legs. Many outdoor retailers provide free pack-fitting services. Use these opportunities to adjust all straps and components with the help of trained staff so your pack fits correctly before heading into the field.

When trying on packs, load them with 15-20 pounds to simulate real conditions. The weight distribution will feel completely different with an empty pack versus a loaded one. Walk around the store for at least 10 minutes to identify any pressure points or uncomfortable spots that might develop into problems on the trail.

The hip belt should be snug enough that you can lift the pack slightly by holding only the belt. If it slips, tighten it. If you can’t fit two fingers between the belt and your body, loosen it. If the pack slides down when you do this test, the belt is too loose. If you can’t get two fingers between the belt and your body, it’s too tight.

The load lifter straps (small straps that connect the top of the shoulder straps to the upper part of the pack) should angle down at roughly 45 degrees when properly adjusted. If the load lifters angle upward, the pack’s frame is likely too long for your torso. If they are nearly horizontal, the frame is probably too short. These straps fine-tune the pack’s position and help pull the weight closer to your back.

Remember that a properly fitted pack will feel almost weightless when you first put it on. The weight should rest primarily on your hips, with your shoulders providing balance and stability rather than carrying the load. If your shoulders are doing most of the work, something in your fit needs adjustment.

Weight Guidelines and Packing Wisely

Carrying too much weight can cause fatigue and injury, turning an exciting adventure into a painful struggle. The BSA Fieldbook recommends that your loaded pack should not exceed 25% of your body weight, though many experienced leaders suggest staying closer to 20% for younger or less experienced Scouts. For a weekend trip, this typically means your pack should weigh no more than 30 pounds.

Healthy adults can safely carry up to 35-40% of their body weight, but Scouts should aim for much less, especially if you’re new to backpacking. Your body is still growing, and overloading can cause real damage to your back, knees, and shoulders. A typical three-season kit including sleeping bag, pad, tent, stove, clothing, and pack weighs about 20 pounds before you add food and water.

The key to safe backpacking is being honest about what you actually need. Every ounce adds weight over miles of hiking. Before each trip, lay out all your gear and ask yourself: “Will I definitely use this?” If the answer isn’t a clear yes, leave it behind.

Smart Packing Strategies

Pack only what you need by reviewing your gear list before every trip. This is about developing the judgment to distinguish between essential and optional gear. Distribute weight so heavier items like your stove, food, and water are close to your back and centered between your shoulder blades. This keeps your center of gravity stable and prevents the pack from pulling you backward.

Use compression straps to stabilize your load and prevent gear from shifting as you hike. Loose items bouncing around inside your pack will throw off your balance and make every step more difficult. Pack your sleeping bag at the bottom, heavy items in the middle close to your back, and lighter items like extra clothes toward the top.

Weigh your packed backpack at home before leaving. This prevents surprises and gives you time to adjust gear if needed. A simple luggage scale costs less than $20 and can save you from discovering your pack is too heavy when you’re already on the trail. Many Scout troops now require pack weigh-ins before departing on backpacking trips.

Remember that these guidelines include everything: your pack, sleeping system, shelter, cooking gear, food, water, and personal items. Water alone weighs about 2 pounds per liter, so factor this into your calculations when planning longer hikes. Start with shorter trips to build your strength and experience before attempting more challenging backpacking adventures.

Must-Have Features for Scout Backpacks

The right backpack features can make the difference between a comfortable adventure and a miserable slog through the wilderness. When you’re carrying everything you need for days on the trail, every design element matters.

The features outlined below are the mechanical inputs that create a successful outdoor experience.

Adjustable torso and hip belts form the foundation of any quality Scout backpack. Your body will change as you grow, and a pack that fits properly today might feel completely wrong in six months. Look for packs with adjustable shoulder harnesses and torso lengths that can adapt as you develop. According to outdoor gear experts, the hip belt should carry about 80% of your pack’s weight, resting on your iliac crest (the bony part of your hips) rather than your waist. This weight distribution prevents the shoulder strain that leads to fatigue and injury on longer treks.

Ventilated back panels address one of the most common complaints from Scouts on the trail: the sweaty, uncomfortable feeling of a pack pressed against your back. Modern suspended mesh systems create airflow between your back and the pack, keeping you cooler and reducing moisture buildup. This feature becomes especially important during summer camps or multi-day hikes when you’re carrying your pack for extended periods.

Hydration compatibility has evolved from a luxury to a necessity for serious outdoor activities. Whether through a dedicated hydration sleeve for a water reservoir or external pockets designed for water bottles, easy access to water encourages you to drink regularly and stay properly hydrated. The BSA Mountaineer 70L Backpack includes both a hydration bladder pocket and a port for the drinking tube, making it simple to sip water without stopping.

Proper organization through multiple pockets and compartments transforms how efficiently you can access your gear. Instead of digging through a single large cavity to find your headlamp or first aid kit, well-designed compartments keep essential items within easy reach. Look for packs with hip belt pockets for snacks and small items, side pockets for water bottles, and a separate sleeping bag compartment that keeps your bedding dry and compressed.

To see how all these features work together, watch this detailed demonstration of proper backpack fitting and adjustment techniques:

Proper backpack fit is essential to prevent pain and discomfort on the trail. Key steps include measuring your torso length, positioning the hip belt on your iliac crest to carry most of the weight, and adjusting shoulder straps, load lifters, and sternum strap for balanced support. These adjustments may need tweaking during your hike to maintain comfort and stability.

Rain covers and durable materials protect your investment and your gear when conditions turn challenging. A quality rain cover should deploy quickly and cover the entire pack, while durable fabrics like ripstop nylon resist tears from branches and rocks. Many Scout troops have learned this lesson the hard way when cheaper packs failed during important trips, leaving Scouts with soggy gear and damaged equipment.

The mechanical relationship between these features and your comfort on the trail is straightforward: better features create better inputs, which produce better outputs in terms of endurance, organization, and overall hiking experience. When you’re evaluating packs, test each feature systematically rather than getting distracted by color schemes or brand names. Load the pack with weight, adjust all the straps, and walk around the store to feel how the features work together.

Compression straps deserve special attention because they serve multiple purposes beyond just making your pack smaller. When your pack isn’t completely full, compression straps prevent your gear from shifting around inside, which maintains your center of gravity and reduces the swaying motion that can throw off your balance. This stability becomes crucial when navigating rocky terrain or crossing streams where balance matters most.

Testing Your Pack Before the Trip

One of the most important parts of backpack preparation happens before the trip begins. Testing your fully loaded pack with a shakedown hike prevents painful discoveries when you’re miles from help. According to the Philmont Scout Ranch equipment guidelines, all gear should work together as one backpacking system that’s been tested through multiple practice hikes.

Start by packing your backpack exactly as you would for your actual trip. Include every piece of gear, food, and water you plan to carry. This is the time to pack all necessary items to test the full weight and bulk you’ll manage on the trail. Many Scouts discover their pack weighs more than expected or that certain items create uncomfortable pressure points only after loading everything together.

Take your loaded pack on a neighborhood walk or local trail for at least 30 minutes. Pay attention to how the weight distributes across your shoulders, hips, and back. Adjust the torso length, shoulder straps, and hip belt until the pack feels balanced and secure. The ScoutSmarts backpacking preparation guide recommends keeping pack weight under 30 pounds for weekend trips, but the real test is how that weight feels after extended wear.

During your test walk, note any discomfort or hot spots where the pack rubs against your body. These small irritations become major problems over multiple days of hiking.  Adjust straps right away if something feels wrong. Tighten loose straps, shift weight, or add padding as needed. Many experienced backpackers recommend doing several test walks of increasing duration to fully break in both your pack and your body’s adaptation to carrying the load.

The mechanical foundation of improvement demands being ruthlessly honest about the relationship between your preparation (inputs) and your trail experience (outputs). If your pack causes pain during a short test walk, it will only become worse over a full day of hiking. Change your packing strategy, adjust your gear selection, or modify your pack setup until the system works smoothly.

Use your test hikes to practice accessing frequently needed items like water, snacks, or rain gear without removing your pack. The best packing system keeps essential items within easy reach while maintaining proper weight distribution. Many Scouts discover during testing that their water bottles are positioned awkwardly or that their first aid kit is buried under other gear.

Document what works and what doesn’t during each test session. Keep notes about strap settings, gear placement, and any modifications you make. This creates a reliable system you can replicate for future trips and helps you troubleshoot problems before they become trail emergencies. The goal is building confidence that your pack setup will support you throughout your entire adventure.

Quick Takeaways

• Choosing the right backpack can determine whether your hiking trip is comfortable or frustrating. Keep these five essentials in mind to choose a pack that will keep you comfortable and prepared on the trail.
• Match your backpack’s size to your trip length and gear needs. A properly sized pack prevents you from carrying unnecessary weight or running out of space when you need it most. Day hikes typically require 15-30 liters, while weekend trips call for 40-65 liters depending on your gear and the season.
• Proper fit starts with measuring your torso and waist accurately. Your torso length determines which pack size you need. Measure from your C7 vertebra to your iliac crest to find your torso measurement, then use that number to select the right pack frame size.
• Keep your pack weight under 30 pounds for weekend trips. The general rule is no more than 20% of your body weight, which means a 150-pound Scout should aim for a maximum of 30 pounds. This includes water, food, and all gear—every ounce counts when you’re carrying it for miles.
• Look for adjustable features and durable materials that will last through multiple adventures. Quality packs include adjustable torso lengths, padded hip belts, and load-lifter straps that help distribute weight properly. Materials like ripstop nylon and reinforced stitching at stress points ensure your pack won’t fail when you’re depending on it most.
• Test your pack fully loaded before your adventure. Pack it with your actual gear and take it on a practice hike around your neighborhood or local trail. This trial run reveals fit issues, hot spots, and balance problems while you’re still close to home and can make adjustments or exchanges if needed.

Frequently Asked Questions About Backpack Selection

How do I know if a backpack fits me correctly?

A properly fitted backpack should feel comfortable and supportive. The hip belt should rest on your hip bones and support about 80% of the pack’s weight. When you buckle and tighten the hip belt, you should feel the load transfer from your shoulders to your hips immediately.

Your shoulder straps should rest comfortably on your shoulders without digging in or sliding off. There should be about an inch of clearance between the top of your shoulders and the shoulder strap attachments. The load lifter straps (the small straps that connect the top of the shoulder straps to the pack) should angle forward at about 45 degrees when properly adjusted. If they’re pulling straight up or angling backward, the torso length isn’t right for your body.

What size backpack should I get for a 3-day trip?

For most 2-4 day camping trips, a pack between 40 and 65 liters will handle your gear comfortably. The ideal size depends on the type and bulk of your gear as well as your trip length. If you’re using lightweight, compact gear like a down sleeping bag and ultralight tent, a 40-50 liter pack might be plenty. Scouts carrying bulkier gear or winter equipment typically need something closer to 60-65 liters.

According to REI’s backpack sizing guide, most backpacking packs start at about 45 liters for good reason. This gives you room for the “Big Four” items (pack, shelter, sleeping system, and cooking gear) plus clothing, food, and safety equipment. Remember that a slightly larger pack gives you flexibility to adjust your gear choices as you gain experience.

Can I use the same backpack as I grow?

Many modern backpacks are designed specifically for growing Scouts and can adapt as you get taller and stronger. Look for packs with adjustable torso lengths, which often provide 3 to 4 inches of adjustment range. Brands like Osprey’s Ace series and Gregory’s Wander packs are specifically designed for youth and feature adjustable torso systems.

The hip belt should also be adjustable or replaceable. Some manufacturers offer different hip belt sizes that can be swapped out as your body changes. This feature is particularly important for Scouts who are still growing, as proper hip belt fit is crucial for comfort and load distribution. Jamborees serve as intensive leadership laboratories where young people develop skills they’ll use throughout their lives, going beyond large camping trips.

Should I buy a rain cover separately?

Whether you need a separate rain cover depends on what comes with your pack and how much rain protection you want. Many quality backpacks include an integrated rain cover, but if yours doesn’t, it’s definitely worth the investment. A good rain cover typically costs $15-30 and can save you from soggy gear and a miserable trip.

Even if your pack is made from water-resistant materials, the zippers and seams aren’t usually waterproof. A rain cover provides an extra layer of protection that keeps everything dry during heavy downpours. Some Scouts prefer using a pack liner (a large waterproof bag that goes inside the pack) instead of or in addition to a rain cover. Pack liners offer protection from moisture that might seep through the pack fabric or enter through the top.

What’s the best way to organize my gear inside the pack?

Smart packing begins with weight distribution. Keep heavier items close to your back and centered between your shoulder blades to maintain balance. This keeps the load stable and prevents the pack from pulling you backward. Your sleeping bag typically goes in the bottom compartment, followed by clothes and other soft items that can fill gaps.

Mid-weight items like food and cooking gear go in the main compartment’s center area. Keep frequently used items like snacks, maps, and first aid supplies in easily accessible pockets. se the pack’s compression straps to keep your gear from shifting as you move. This maintains your balance and makes your pack feel more stable.

Consider using packing cubes or stuff sacks to organize smaller items. This makes it much easier to find what you need without unpacking half your gear. Keep your rain gear and extra layers near the top or in an external pocket where you can grab them quickly when weather changes.
