We designed the RADIX 31 with three things in mind: speed, versatility, and durability. With its lightweight design, it’s a delight for the ardent peak bagger and ambitious day hiker alike.  ![]()
The RADIX 31 was designed knowing a little less weight can make your mountain mission a whole lot better. Crafted from lightweight Ultra-PE Birdseye and durable, recycled Robic Ripstop fabric, this pack takes the edge off those grueling ascents without sacrificing toughness. An array of adjustable features, like a removable frame, and plenty of external pockets helps you master the game of cubic inches. And the option of women’s or men’s harnessing provides a natural and comfortable fit.
