4400 SERIES 70-LITER HIKING BACKPACKS

Our 70-liter hiking backpacks are designed to help you hike, climb, packraft, and bike more efficiently, with less fatigue and pain, using gear that is so light and simple it becomes an afterthought. Our award-winning made-in-the-USA backpacks are all built with virtually waterproof Dyneema® Composite Fabrics and rigorously tested by some of the most acclaimed explorers in the world. While similar to our smaller 2400 and 3400 pack versions, this backpack has a wider circumference, is made from burlier material and has additional elastic frame sheets that offer greater load carrying capacity.

The Windrider’s mesh pockets make it an excellent choice for quickly finding gear you’ll want to access throughout the day, or to dry wet gear as you hike. Choose the Southwest for added abrasion protection in rockier environments where scrambling, bouldering, or navigating narrow crevasses are likely, or you just want to keep pocket contents hidden. Both of our packs are also great for travel. Click on a backpack below to get more details on each 70L hiking pack in our line.
