Lightweight and comfortable Aether 70 is a versatile pack with adequate space and organization for weekend or weeklong trips lasting 3 to 7 days. The bestselling backpacking series on the market just got even better. Known for its ability to be taken all over the world, from the summit of Everest to a backpack trip through your local wilderness, the fourth generation of Aether builds upon its reputation for combining clean design, custom fit and outstanding load carrying comfort. Amongst a plethora of upgrades, the new IsoForm CM hipbelt adds stiffness and padding for even better performance with heavy loads. Amazingly, all this comes with no increase in weight.
