When you're counting every ounce but you know the value of a truly comfortable pack, the Exos was developed just for you. Reach for the Exos 48 for the perfect mid-size ultralight, with plenty of room to put in the miles, but not so much that you're tempted to overpack. Highly experienced backpackers will appreciate industry-leading comfort and ventilation—without the weight it often adds—making it the perfect pack for ultralight multiday adventures. For those who really need a svelte carry, the removable floating lid makes way for an integrated FlapJacket that keeps your minimal gear contained in its stead. Our refined AirSpeed® suspension keeps you cool with maximum airflow between you and your pack, so each mile stays as comfortable as the last. Made with 100% recycled materials.
