A good pack disappears. A bad pack argues with you all day — hot spots on your hips, shoulder straps that bite, a load that swings when you step over rocks. This guide is about buying the pack that stays quiet.
Quick picks
- Day hiking: 18–28L for most people.
- Big day / camera / extra layers: 28–35L.
- Overnight to 2–3 nights: often 45–65L depending on your sleep system.
The only 3 things that matter first
- Fit (torso length + hipbelt shape)
- Load carry (frame + stays + how it transfers weight)
- Access (how quickly you can get to the things you use often)
How to size capacity without guessing
- If your sleeping bag/quilt and pad are bulky, you need volume.
- If you carry bear canisters, pack choice gets narrow fast.
- If you “pack fears” (extra everything), you’ll buy too big and then overpack. Be honest.
Daypack vs backpacking pack
| Type | Typical liters | What you gain | What you give up |
|---|---|---|---|
| Daypack | 18–35L | Light, fast, simple | Less comfortable with heavy loads |
| Backpacking | 45–75L | Load transfer, stability | Weight, complexity |
What to look for (outdoorsman checklist)
- Hipbelt that grabs your hips (doesn’t float)
- Shoulder straps that match your shape
- Ventilation that helps but doesn’t compromise carry
- Side pockets you can reach while walking
- Compression straps that actually stabilize loads
Common mistakes
- Buying based on liters alone
- Buying ultralight before your kit is truly compact
- Not considering water carry (bottles vs bladder)
