What Hunters Need in a 40L Pack
Hunting packs use quiet fabric that does not rustle, carry systems for a rifle or bow, and room for layers, water and calls. A rain cover and hydration port help on long sits. If you plan to pack out meat, choose a frame pack built for heavy loads. Related: our shortlist of the best 40L camera backpack.
Tactical and Military-Style 40L Packs
Tactical packs use heavy fabric, MOLLE webbing and many compartments, which makes them tough and easy to customize with pouches. The trade-off is weight and simpler harnesses than hiking packs. They work well for rucking, range days, travel and emergency kits; for long hikes, a framed hiking pack carries heavy loads more comfortably.
How to Fit a 40L Backpack
Fit matters more than brand. A 40-liter pack with the wrong torso length will hurt even if it is made from the best fabric. Measure your torso from the bony bump at the base of your neck (the C7 vertebra) down to the top of your hip bones. That number, usually between 15 and 21 inches, tells you which size or adjustment range to choose. If you are comparing options, our guide to the best 40L backpack travel picks is worth a look.
Load the pack with about 15 pounds before you adjust it. Then follow this order:
- Hip belt first. Center the padding on your hip bones and tighten until it carries most of the weight.
- Shoulder straps second. Pull them snug so they wrap your shoulders without lifting the hip belt.
- Load lifters third. On framed packs, angle them about 45 degrees to pull the top of the pack toward you.
- Sternum strap last. Clip it about an inch below your collarbones, just tight enough to stop the straps from sliding outward.
If the shoulder straps leave a gap above your shoulders or the hip belt sits on your waist instead of your hips, the torso length is wrong. Packs with adjustable back panels, like the Osprey Kestrel and Kyte, solve that without exchanges.
What Fits in a 40L Pack
A 40-liter pack is enough for a fast overnight in summer, a hut trip, or a week of travel if you pack light. A typical summer overnight load looks like this:
- Ultralight one-person tent or hammock (2 to 4 liters packed)
- Compressible sleeping bag rated for the season (5 to 8 liters)
- Inflatable sleeping pad (1 to 2 liters)
- Stove, fuel and small pot (2 liters)
- Food for one to two days (3 to 5 liters)
- Rain jacket, warm layer and spare socks (5 liters)
- Water: 2 to 3 liters in bottles or a bladder
- Ten Essentials: navigation, headlamp, sun protection, first aid, knife, fire, emergency shelter
If your sleeping bag is bulky synthetic, or you hike in shoulder season with heavier layers, step up to a pack with an extension collar or roll-top, like the Naturehike Rock 40+5 or Haimont 40+15. For travel, 40 liters holds about five to seven days of clothes with packing cubes. For a closer look, see our guide to the best 40L backpack for travel.
30L or 40L: Which Should You Choose?
Choose closer to 30 liters if you mostly do day hikes, carry little water or hike in warm weather. You will have a lighter, slimmer pack that is less tempting to overfill. Choose 35 to 40 liters if you hike in changing mountain weather, carry gear for kids or a partner, or want the option of a summer overnight. The extra 10 liters mostly add flexibility, and compression straps make a part-full 40L pack carry like a 30L one.
