When you're counting every ounce but you know the value of a truly comfortable pack, the Osprey Men's Exos 48 - L/XL 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 often added—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.
