Designed to improve your posture while active, this innovative top features ODLO's award-winning Active Spine Technology, incorporating a stabilizing element on the back into an ultra-light and breathable Zeroweight Eyelet mesh first layer. With its body-mapped compression and elasticity zones, the top works to support the spine and pull back the shoulders, reducing slouching. This in turn opens the chest, resulting in increased oxygen intake. Ideal for trail running, gym, backpacking or simply for everyday wear.
