Log miles — this adidas half-zip running tee keeps you covered and comfortable while you're at it. AEROREADY manages moisture to keep you dry, and thumbholes keep the sleeves in place through every stride. A reflective logo on the chest lights up in dim light, a reminder of the legendary race you're training for. This product is made with at least 70% recycled materials.
