Yup - with the big pockets!

We designed the 4400 Southwest for remote, multi-sport trips to inhospitable regions, where resupplies are infrequent. Made from 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber) and with additional elastic frame sheet support for extra load carrying capacity, this ultralight pack is highly durable. Fortify your pack with our Stuff Sacks for a waterproof finish.
