Consider your activity:
- Hiking: Often compatible with hydration reservoirs, have external gear straps/loops
- Running: Designed to limit bounce, hydration compatible
- Climbing: Slim profile, abrasion-resistant reinforcements
- Traveling: Multiple compartments, meets carry-on requirements
- Cycling: Road cycling packs compact with lower profile; MTB packs hold more gear
How much gear will you carry?
- 10L or less: Short runs, quick outings, casual use, essentials only
- 11–20L: Day hikes, cycling, can carry an extra layer
- 21–35L: Sweet spot for multi-hour or full-day hikes, travel
- 36–50L: Gear-heavy outings l(all-day hikes, climbing), winter hiking, ultralight backpacking
Internal frame or frameless?
- Internal frame: More support for heavier loads, but bulkier
- Frameless: Lighter weight and more compact, but less support
