When you need a bottom layer that offers protection from the trail but wont slow you down, wear the heavyweight Mens Trinity 10 Shorts. Tough and durable, their stretch-nylon fabric resists abrasions even if you encounter rocks, dense foliage, or other debris, and the gusseted inseam increases your range of motion. Rain clouds moving in? The DWR (Durable Water-Repellent) finish keeps you dry so you dont have to think twice about forging ahead. If the forecast calls for the opposite, built-in UPF-50 shields your skin from the sun. Secure small hiking gear in one of five pockets.
