Ideal for all runners, the top compression reinforced in the most exposed places and studied for a very good evacuation of perspiration offers all the guarantees of a comfort and a strength that one is entitled to expect to a high price admittedly (but price is equivalent to the competition for uen comparable quality). Tested on 5 outputs an hour, by fine weather and rain, I consider that this top is an element of comfort for all athletes who wish to combine simplicity and quality.
