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 AirSpeedsuspension 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.
