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 that it becomes an afterthought. Our award-winning backpacks are all built with waterproof Dyneema® Composite Fabrics, and rigorously tested by some of the most acclaimed explorers in the world. While aesthetically similar to our smaller 40L and 55L pack versions, the 70-liter versions have a wider circumference, are made from burlier material, and offer additional plastic frame sheets for greater load-carrying capacity.
