The Relentra Performance t-shirt is incredible. I personally have hyperhidrosis which makes me sweat more than the average human, mix that with long distance endurance events and you have a recipe for a rough day. But no more thanks to the new the incredible material and design. Its incredible fit & lightweight material has been great to get me back running. I recommend this product to anyone looking for a great shirt that is comfortable, stylish and can perform when you need it to most.
