Patagonia Boys' Backpacks

Choose your fit

• Standard or straight: consistent leg width
• Slim: tighter or tapered to the leg
• Relaxed or wider: fits loosely throughout the thighs, knees and calves

What material do you prefer?

• Synthetic
• Polyester: affordable, stretchy, doesn't wrinkle
• Nylon: durable, abrasion-resistant, less stretch
• Spandex: stretchy, moves easily, less breathable
• Natural fibers
• Cotton: durable, breathable, dries slower
• Wool: stretchy, durable, odor-resistant, pricier
• Hemp: durable, renewable, not as soft

Additional features

• Moisture wicking: moves sweat to the outer surface while also drying quickly
• Pockets: zippered pockets offer more security
• Sun-protective fabric: higher UPF rating means better sun protection
• Convertible: can be worn full-length or as shorts
• Insect repellent: treated with coatings can help keep pests off

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
