I am delighted by this tshirt !! and my darling who I've offered is very happy too! I put the rating of 4/5 for this shirt because I found one caveats: the neck, it relaxes a little, by dint of passing the head, but it does not interfere with the aim and effectiveness of this T Shirt;) !! My boyfriend is going to run with this shirt, and with his teammate, he's had a normal shirt and was soaked, and my boyfriend stayed dry! He is delighted !! In addition it visually highlights. Beautiful and efficient !! I recommend this product to anyone who sweats easily (during workout or even during the day (in a shirt? Etc) I advice hand wash !! it dries quickly all manner. and to pay attention to size! if you find yourself between two sizes (in my case, these measurements were battery between S and M> Enjoy!
