The incredible seamless technology of this LTK SEAMLESS LIGHT TS SS trail running T-shirt means breathable sections have been located ergonomically to optimise ventilation during intense exertion. This technique avoids chafing seams and additional weight as well as keeping all the elasticity you need to maximise your performance. The fabric of this super light men's T-shirt dries instantly so you don't get chilly when the wind starts to blow along the mountain trails. It features a POLYGIENE® coating as a barrier to the development of unpleasant smells and thus gives you a long-lasting sensation of freshness.
