Rain or shine. Short or long. You love it all and wouldn't dream of skipping a day on account of a little heat. Crafted from recycled materials specifically for performance, the ODLO Zeroweight Chill-tec running t-shirt is made for warm weather running when pace and temperatures are inextricably linked. Designed for maximum cooling, it's finished with reflective details for those who want to push another 5k, even as the light fades.
