By Activity
- Hiking: can hold a water reservoir and available in different torso sizes for right fit
- Climbing: narrow profile, abrasion-resistant reinforcements
- Traveling: pockets or compartments for organization, carry-on size
Capacity
- Packs that hold 20L or less are best for runs, day hikes, mountain biking or short trips.
- Packs between 20–35L are great for longer day hikes and as a travel carry-on.
- Packs holding 35–50L work for extended trips and mountaineering or climbing that calls for extra equipment.
Fit
The right daypack fit offers:
- A size appropriate for your torso length (not your overall height)
