The MYSTERY RANCH Radix 57L Backpack is the versatile, durable companion with us when we show up in the parking lot with dirt, sweat, and a smile gracing our faces after racking up miles on the trail. The lightweight Ultra-PE Birdseye and Robic ripstop materials are built to handle any condition, ensuring our gear stays safe and compact no matter what the trails throw our way. The lightweight aluminum frame can be removed when we are prioritizing moving light and fast or be left in to provide structure for our gear. Compressible side and front pockets stash away our quick-access items like layers and snacks, and the front hip pockets hold our phone, GPS, and multi-tool. The adjustable harnessing options keep the bag sitting comfortably on our hips and provide a gender-specific, ergonomic fit.
