Jogging, trail running or speed hiking–you love pushing yourself to your physical limit. The Mens Sierra Tee will help you get there. This T-shirt is made of an agile, stretchy fabric and has a casual, sporty cut. The fabric blots up perspiration efficiently, wicks it away from the skin to the outer surface and dries quickly. The Hydropore fabric has several additional attributes that support your physical performance during high-output activities. It's super stretchy and specially treated to eliminate unpleasant odours.
