4400 Windrider

Adding to cart… The item has been added


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, Hyperlite Mountain Gear made this rucksack for big packrafting adventures to the Brooks Range of Alaska, 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 (sold separately).

Please note, Hyperlite is phasing out the grommets on the weep holes of their pack pockets. This product may ship with or without grommets. For more info, see the Tech Specs & Features section.

After a number of internal studies, Hyperlite has decided to remove the metal grommets from the weep holes of their packs. This product may ship with or without the grommet as they are phased out from Hyperlite's inventory.
The grommets were not an essential feature to the weep holes of the pack. Hyperlite has determined there is no physical function of these grommets and they have been merely for aesthetic purposes. Their design and production team has developed a consistent method of precision drilling the holes in the fabric. The heat generated from the friction from this process will seal the edges of the weep holes and eliminate the chance of the fabric fraying. This will now make the holes just as strong as when constructed with grommets.
