Hyperlite Mountain Gear 4400 Southwest UltraLight Pack HMG UL Backpack

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. Further weatherproof your kit by using our Stuff Sacks. Add extra storage space with a Porter Stuff Pocket.
