Osprey Internal Frame Cycling

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
• 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

Find the right fit

• Use torso length (not overall height) to find your pack size

• Measure your hip circumference (slightly higher than your pant-waist size) and check that against the hipbelt size
