The UD Fastdraw 350 is a highly refined bottle tailored to the unique requirements of the distance runner. The ergonomically shaped bottle is comfortable in the hand for hours of grinding on Eastside trails. The strap is made from Cool Wick Air Mesh—a feather-light breathable material—and finished with a soft, chafe-free edge binding. A simple adjustable strap lets you dial in the fit on your hand so that holding the bottle is effortless. For storage, there’s a zippered compartment with a clip to keep your keys secure, plus additional space for a bar, small phone, or personal beacon. The stretchy mesh outer pocket has a Velcro closure and is perfect for gels, lip balm, or other on-demand necessities. When a good day starts in the sage brush and tops out with awesome views back toward Bishop, this is the handheld to bring along.
