How to Choose a Backpack: Capacity, Frame, and Fit
Size the pack to the trip, let the hip belt do the carrying, and never let total weight pass 25% of your body weight.
In short
Match pack capacity to trip length: 15–30 L for day hikes, 30–50 L for 2–3 light nights, 50–70 L for 3–5 nights with full camping gear, and 70 L or more when you must carry heavy resupply. Whatever the size, keep total pack weight under about 25% of your body weight, and make sure the hip belt — not your shoulders — carries roughly 70% of the load.
Sizing the Pack
| Trip type | Capacity | Notes |
|---|---|---|
| Day hike | 15–30 L | Water, lunch, first aid kit, rain jacket |
| 2–3 nights, light | 30–50 L | Sleeping bag required; the tent can be shared |
| 3–5 nights, fully loaded | 50–70 L | Full camping kit plus several days of food |
| 5+ nights | 70 L or more | Heavy resupply; watch total weight |
The Suspension
- Aluminum-frame packs: carry heavy loads well; best for 33 lb (15 kg) and up.
- Mesh-back panels: ventilate well; best for loads under 22 lb (10 kg).
- Adjustable torso: adapts to different torso lengths; good for sharing a pack.
The Fit Check
- Load about 22 lb (10 kg) of weight into the pack and walk around.
- The hip belt should sit on your hip bones and carry about 70% of the weight.
- Shoulder straps should hug the shoulders without pressing on them.
- Clip the sternum strap just below your collarbone.
