The REI Co-op Trailmade 10 Hydration Pack is a low-profile 10-liter pack sized just right for short hikes when a full-size daypack is more than you need. It includes a 1.5-liter HydraPak Elite hydration reservoir to keep you hydrated on the trail.
An air mesh back panel and mesh shoulder straps provide ventilated comfort on warm days, while the zip panel opening gives easy access to the main compartment and a zippered front-panel pocket keeps smaller items like a phone within reach. Lash loops let you tether extra gear, and a durable water repellent (DWR) finish made without PFAS helps moisture bead up on the surface.

How to Choose Daypacks?
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 (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.
