Clean lines, burly fabric and 2 daisy chains for clipping on extra cargo define this great bag. The Roll Down Pack is designed for the ever-changing seasons climbers face. In winter, expand the bag to its 2000 cubic inch max to carry extra dry, warm clothes, and in summer, roll down the extra space in the bag to its 1362 cubic inch minimum. This versatile pack features a 1050d ballistic nylon shell with a ballistic nylon bottom cap and sewed the body out of a timeless X11 Cotton Canvas X-PAC, as well as a large inside zip pocket and key clip for safe-keeping of keys and other valuables. Die-cut ergonomic shoulder straps, sternum clip and hip belt combine to create a balanced ride on your back. Bright Orange Liner on Back panel side helps light up the inside of bag! As the material matures it gains an authenticity about it with the subtle X-grid gaining more texture over time.
