Camping Backpack Guide: How to Choose the Right Pack

How Many Liters Do You Actually Need?

Backpack capacity is measured in liters and generally falls into four categories. Your choice depends on trip duration, gear volume, and whether you carry shared equipment. For a deeper dive into packing strategies, see our backpacking checklists.

Capacity Range	Best For	Typical Use Case
20–35 liters	Day hikes, summit pushes	Essentials only: water, snacks, rain shell, first aid
35–50 liters	Overnight or minimalist weekends	Light sleeping bag, small tent, stove, 1–2 days of food
50–70 liters	3–5 day trips	Full camping kit, bear canister, multiple days of food
70+ liters	Extended expeditions, family gear	Winter gear, group equipment, 7+ day treks

If you are new to backpacking, a 50–60 liter pack is a versatile starting point. It handles weekend trips comfortably and forces you to pack thoughtfully—a skill that pays off on every adventure. For those transitioning from car camping, our camping for beginners guide can help you bridge the gap.

Torso Length, Not Height, Determines Fit

Backpack sizes are based on torso length—the distance from your C7 vertebra (the bump at the base of your neck) to your iliac crest (the top of your hip bones). This measurement, not your overall height, determines whether a pack will carry comfortably. Most manufacturers offer packs in small, medium, and large torso ranges, with some offering adjustable suspension systems.

Key fit checkpoints:

• Hip belt: Should wrap around your iliac crest and carry 60–80% of the load. If it sits above your hips, the pack is too short.
• Shoulder straps: Should curve over your shoulders and anchor just below the collarbone—not digging into your neck or floating above your shoulders.
• Sternum strap: Adjustable and positioned mid-chest to keep straps from slipping.
• Load lifters: Small straps at the top of the shoulder straps that pull the pack closer to your body and reduce sway.

Always try a pack on with weight inside—ideally 10–15 kg—before committing. A pack that feels fine empty may become unbearable after a few hours on the trail. If you plan to camp in colder conditions, our winter camping gear guide explains how bulkier insulation affects pack choice.

Internal vs. External Frames

Modern camping backpacks almost universally use internal frame suspension, where a frame sheet or stays sit inside the pack body. This design keeps the load close to your center of gravity, improving balance on uneven terrain. External frame packs—once the standard—are now niche products, mainly used for heavy loads on maintained trails.

Within internal frame packs, you will encounter three broad tiers:

• Entry-Level — Simple framesheet with basic padding. Adequate for light loads under 12 kg on easy trails.
• Mid-Range — Adjustable suspension, better ventilation, and more refined hip belts. Handles 15–20 kg comfortably.
• Premium — Customizable fit, advanced materials, and superior load transfer. Designed for heavy loads and long distances.

Ventilation is another consideration. Trampoline-style back panels keep the pack off your back for airflow, which is valuable in humid climates. Traditional foam panels sit closer to your body, which can feel more stable on technical terrain. Neither is universally better—match the system to your environment. If you often camp in hot, humid areas, pair a ventilated pack with strategies from our camping hygiene guide to stay comfortable.

Prioritize Function Over Gadgets

Backpack marketing is full of buzzwords. Here is what actually matters on the trail:

• Access: Top-loading packs are simple and light. Panel-loading packs (with a U-shaped zipper) offer easier access to buried gear. Many modern packs combine both.
• Pockets: Side pockets for water bottles, a hip belt pocket for snacks or a phone, and a lid pocket for quick-access items are genuinely useful. Too many pockets add weight and confusion.
• Hydration compatibility: A sleeve for a water bladder and a port for the hose are standard on most packs. If you prefer bottles, ensure side pockets are deep enough to secure them.
• Rain cover: Some packs include one; others sell it separately. A rain cover is lighter and more effective than a pack liner for moderate rain, but a liner protects gear even if the pack is submerged. For serious wet-weather camping, read our tips on camping in a tent in the rain.
• Compression straps: Allow you to cinch down the load as consumables (food, fuel) run out. Essential for stability.
• Attachment points: Loops and daisy chains for strapping on trekking poles, ice axes, or a sleeping pad. Useful, but do not overload the exterior—it throws off balance.

Features to approach with skepticism: built-in speakers, complex modular systems you will never reconfigure, and "ultralight" claims on packs that weigh more than established competitors. Focus on fit, suspension, and durability first.

What Your Pack Is Made Of

Most camping backpacks use nylon or polyester fabrics, often with a denier rating (e.g., 210D, 420D, 1000D). Higher denier means thicker, heavier, and more abrasion-resistant fabric. A 210D ripstop nylon is common on ultralight packs, while 420D–600D fabrics balance weight and durability for general use. Expedition packs may use 1000D Cordura for maximum toughness.

Considerations:

• Ripstop: A grid pattern that stops tears from spreading. Nearly universal in quality packs.
• Coatings: Polyurethane (PU) or silicone coatings add water resistance. PU is more common and easier to repair; silicone is more durable but harder to patch.
• Zippers: YKK is the industry standard for reliability. Look for zippers with storm flaps on exposed pockets.
• Buckles: Duraflex and YKK are trusted brands. Cheap buckles are a common failure point on budget packs.

If you camp in abrasive environments—granite slabs, desert scrub—invest in a higher-denier pack or accept that you will replace it sooner. For most campers, a mid-range fabric with quality hardware will last many seasons. Our guide to how long tents last applies similar logic to gear lifespan.

Fit Differences Are Real

Women's backpacks are not simply men's packs in different colors. They typically feature:

• Shorter torso lengths
• Narrower shoulder straps shaped to avoid chest pressure
• Curved hip belts designed for a wider hip-to-waist ratio
• Sometimes a different suspension geometry to accommodate a lower center of gravity

That said, fit is individual. Some women fit men's packs better, and vice versa. The label matters less than how the pack carries on your body. If you are shopping for a family member or partner, our camping with kids checklist includes tips for selecting gear that works for different body types.

Weight Distribution Makes or Breaks Your Trip

Even the best backpack will feel terrible if packed poorly. Follow these principles:

• Heaviest items close to your spine and at mid-back. This keeps the weight over your hips and reduces strain on your shoulders.
• Light items at the bottom and top. Sleeping bag at the bottom, puffy jacket and rain gear near the top for quick access.
• Frequently used items on the outside. Snacks, map, sunscreen, and water in hip belt pockets or side pockets.
• Balance left and right. A lopsided pack causes you to lean, leading to fatigue and injury.
• Keep the load compact. Use compression straps to eliminate empty space. A tight pack moves with you; a loose pack shifts and rubs.

Make Your Backpack Last

A quality backpack is an investment. Protect it with simple habits:

• Clean after every trip. Empty all pockets, shake out debris, and wipe down with a damp cloth. For deeper cleaning, use mild soap and water—never machine wash.
• Dry thoroughly before storage. Mildew is the enemy of coated fabrics. Store in a cool, dry place, ideally hanging or loosely packed.
• Repair promptly. Small tears can be patched with Tenacious Tape or seam grip. Replace broken buckles before they fail on the trail.
• Check zippers. Lubricate with a zipper wax or silicone spray if they start sticking.
• Do not overload. Exceeding a pack's comfortable weight range stresses seams and suspension.

With care, a well-made backpack can serve you for a decade or more. For more gear longevity tips, see our article on whether expensive tents are worth it—the same principles of quality and care apply.
