If you're a serious backpacker that needs a Pack that can keep up with your adventures, then you need the Cascade 90 from ALPS Mountaineering. It uses a tubular frame design rather than traditional aluminum stays-so it stays lighter. Plus it sits more snuggly against your body to better distribute the weight. Its spacious design provides up to 5,500 cu. in. (90L) of carry space to fit all your necessary gear. Easily access anything through the top-loading lid or zip-close lower compartment. The lid with zipper pocket is removable, so take it off and wear it as a fanny pack when you want a lightweight option for exploring near camp. You'll appreciate these features and more for all of your cross-country adventures.
