The Skala 40L Hiking Pack is built for ambitious day hikes that call for more gear and greater range. A lightweight AlumaLite frame provides structural support for effective load carriage, while load lifters and an adjustable harness (offered in S/M and L/XL sizing) dial in a personalized fit. The pack uses 420 HD nylon with a durable carbonate coating on the exterior for weather resistance, 210 nylon Birdseye Dobby reinforced with UHMWPE fibers in high-abrasion zones, and a padded, vented mesh back panel and harness for breathable comfort. A pull-to-open RipZip main compartment gives quick access to gear, stretch-woven hydration holsters keep water within reach, and YKK AQUAGUARD zippers seal out the elements. It is covered by YETI's 3-year limited warranty and is compatible with hydration reservoirs up to 3L, YETI Yonder water bottles and packing cubes, and select Mystery Ranch accessories.
