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 we face as climbers. 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, 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!
