HMG 4400 Windrider
The solution to the high-volume pack that weighs too much before it’s even loaded, the 4400 Windrider is ideal for expeditions and multi-sport adventures where resupplies are infrequent. Made for extreme environments, we designed these ultralight packs with 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber) and additional elastic frame sheets that provide support for extra load carrying capacity. Complement this pack with organizing, weatherproofing Stuff Sacks.
