This 3D-FLEX® SPRINT men's T shirt, which has been tested and approved by our ambassador Florian Olivier, offers excellent muscle support under the chest and improved posture during racing or trail running training and competitions. It encourages oxygenation when running, thus improving endurance and recovery, making you more effective for longer.

Review by the CimAlp trail ambassador, Florian Olivier:
"An effective, pleasant-to-wear T shirt for long or short trails. I wore it on the Vercors 2014 ultra trail (very warm) and it kept all its promises: no irritation, ideal muscle support and efficient heat regulation."

Size great, well made, a little tight but not unbearable. Perhaps the only downside breathability when used in hot weather. This remains a very nice shirt.
