Providing all the features and capacity you need and nothing more, the Fastpack 20 is a streamlined pack that will get you there and get it done. Perfect for day hikes, peak bagging, or a quick weekend, the Fastpack takes inspiration from Ultimate Direction's Signature Series vests, with its super stable and comfortable fit. There is easy access to water, maps or your phone on the front, the stretch pockets on the sides will hold almost anything, and the huge rear stretch pocket allows gear to be quickly stowed or used as needed. The main compartment forgoes zippers in favor of a waterproof roll top closure, allowing this bag to tightly secure everything from 15 to 23 liters. The Fastpack 20 is water-resistant, with a reinforced bottom panel for extra durability, and the low-profile daisy chains with trekking pole and ice axe loops complete the package. Unique to the Fastpack is Ultimate Direction's InfiKnit construction: the back panel and shoulder straps are made from one piece of custom-made fabric, which eliminates contact with all seams.
