The X-Alp Performance Wool 115 trail running shirt by ODLO is a running shirt that is second to none: it is lighter, more robust and dries faster than conventional merino clothing.The stylish fine stripe T-shirt is made from Performance Wool developed by Nuyarn® - a wool blend that has very similar performance properties to wool. Naturally thermo-regulating, it cools when it's warm and warms when it's cold. It is also naturally antimicrobial (i.e. odor-inhibiting). Made from mulesing-free merino wool, the functional material dries five times faster than normal merino clothing and is more than eight times more abrasion-resistant - perfect if you are planning longer trail runs or are traveling with a running backpack.
