Our Pro Athletes in Ski-Mountaineering , Trail Running, Cycling were after the lightest possible baselayer with maximum thermoregulation.
3D Knitting Structure

The 3D knitting structure regulates temperature variations and helps the body to keep an even temperature to perform at its best.

The 3D knitting generates thermo layers composed of ventilation channels and air cushions. Thanks to these different layers, the garment is not in direct contact with the skin. It enables a flow of ventilated air and acts as a thermo regulator between the skin and the outside air.

Optimal Thermoregulation for maximum performance The 3D Thermo Ultralight Shirt is the ideal base layer for cold protection and to stay dry. It enables the body to perform at its maximum potential in cold environments: The body will not need to spend energy to regulate its temperature but to use this energy to perform at its best!

TRUE STORY The request: Our Pro Athletes in Ski-Mountaineering , Trail Running, Cycling were after the lightest possible baselayer with maximum thermoregulation. A featherweight first layer garment that would protect them against the cold, that wicks moisture, and stays dry.

Your COMPRESSPORT® do not retain water and will remain featherlight in all conditions. For optimum comfort, the microfibre body of the TRIATHLON SHIRT is 100% seamless, lightweight and very soft. Woven directly into the fabric, the light Spin Control compression zone helps to hold you up straight during workout, realign the shoulders, remain in the proper position even during long workouts. The long-sleeve and short-sleeve models include 3D patches providing localized, maintained compression to the muscles of the arm (biceps) and the forearm (supinator and pronator teres), and providing optimum shock absorption as well as an anti-vibration effect.
