The Pyr (a slimmed down version of Gregory’s Icarus) is designed for shorter, lighter outings and mountain biking. The Pyr offers just enough space (1,150 cubic inches) to carry what you need for a lightweight day out or a big adventure on your mountain bike. The pack features zip-through access to your hydration system, a large main compartment, an expandable exterior stuff-it pocket that will hold a helmet or extra layers, and four side pockets for energy gels, food, or an iPod.

A webbing waist belt keeps things slim for use on the bike, but attaches into the pack’s body at multiple points, for a snug ride. A breathable AeroTech mesh back panel ensures airflow and siliconized G30 fabric keeps things light.
