The Trail Short was designed to carry you through the longest of runs. The incredibly soft 4 way stretch fabric used for the Trail Short is extremely light weight and the forward angled side seams reduce fabric drag and resistance during your natural running motion. The Trail Short is built with a supportive cool max boxer brief style liner and reverse seam construction to eliminate chaffing. Moisture wicking, quick drying, reflective logo hits, and an iPhone stash pocket make this short perfect for any activity. The Trail Runner is a 17.5" outseam, making them the shortest short in the Vuori offering.
