The Exos provides backpackers with an unbeatable combination of comfort, ventilation, function in a lightweight package. It works great for weekend trips and depending on your packing style can go way further. The incredibly comfortable Exoform harness and AirSpeed ventilated suspension combine with trail-friendly features like Stow-on-the-Go trekking pole carry. Ultralight doesn't have to mean uncomfortable, and the Exos proves this.
