Make sure you head to the trails prepared with the Ampex Cahill Excursion 25-Liter Framepack Backpack on your back. The Bluesign recycled polyester construction resists wear and tear out in the elements, and the multiple storage options and hip belt pockets deliver lots of space for all of your gear and items. A ventilated back panel and shoulder straps help you stay feeling cool and comfortable, and the adjustable frame, sternum strap and hip belt allow you to tighten or loosen the backpack to your perfect fit.
