As a female backpacker, this is one easy to use pack. It’s fast, lightweight, and I hardly feel it on my back. Stripped down and high-performance, we dialed in our 3400 Southwest Pack to meet the exacting requirements of multi-day adventurers. Made with ultra-durable, 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber), this pack excels in rugged environments. This is also a great day pack to get outdoors, hit the trail and enjoy.
