The North Face Reaxion Redbox T-Shirt The Reaxion Redbox T-Shirt is a great all-round training tee that keeps you fresh as you work up a sweat. It's made with FlashDry fabric that wicks moisture away from your skin, so you stay cool and dry. Wear the authentic The North Face logo loud and proud on the back. Enriched with FlashDry technology, the Reaxion Redbox T-Shirt offers enhanced moisture management and quick-drying properties to keep you feeling dry and comfortable throughout training sessions. This quick-drying fabric wicks moisture and sweat away from the skin's surface and pushes this to the outer layer of the top where it can be quickly evaporated. This reduces the weight and keeps you moving light and fast when things heat up. A regular fit ensures an easy, comfortable style for added comfort during wear.
