Hyperlite Mountain Gear - 4400 Windrider

The solution to the high-volume pack that weighs too much before it’s even loaded, the 4400 Windrider works in extreme environments where resupplies are infrequent. Ultra strong, lightweight and durable, we made this rucksack for big packrafting adventures to the Brooks Range of Alaska or massive thru hikes or multi-sport adventures where resupplies are infrequent. Whatever your expedition, this ultralight backpack will carry everything you need and nothing you don’t. Voted Backpacker Magazine’s “Best Ultralight Pack,” the Windrider Packs are made from 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber). This 70L pack has additional elastic frame sheets that provide support for extra load carrying capacity. Complement this pack with organizing, weatherproofing Stuff Sacks.
