Hyperlite Mountain Gear 4400 Southwest


Durable yet lightweight, the Hyperlite 4400 Southwest backpack is the perfect travelling companion for when you’re tackling your next outdoor adventure. 


Be prepared for those longer adventures thanks to the substantial volume of the Hyperlite 4400 Southwest – this big boy has enough space for a week’s worth of supplies, including cold weather gear, fuel and food. Yet, the composition of the Hyperlite backpack ensures it doesn’t become a burden.

The Hyperlite 4400 Southwest is made from incredibly sturdy, strong, and water resistant Dyneema® Composite Fabrics, which are the manufacturer’s own materials.

The largest-size of the Southwest range of Hyperlite backpacks, the 4400 offers a 70L internal volume – slightly more than the Hyperlite Southwest 3400 (55L) and much more than the Hyperlite Southwest 2400 (40L).
