"It is the lightest baselayer I have worn and it is amazingly comfortable!" Our 2016 UTMB winner Ludo Pommeret is one of the pro athletes for whom we originally designed the lightest possible baselayer with maximum thermoregulation.The high-tech 3D weave takes care of all ventilation and temperature control, thanks to the air mattress created between air and skin. Without these key elements to worry about, the body can focus all energy on performance. The 2020 updated version uses a new weave to improve durability and save weight. Fabric resistance is improved yet the shirt feels as soft and light as a second skin, so you can forget what you're wearing and concentrate on the trail ahead. Posture support is woven directly into the shirt, helping keep shoulders straight and aligned even after long hours of effort. The Raglan sleeves provide localised compression for extra support and freshness on the upper arms.Created for pure performance, the shirt is destined to be worn as an ultra-efficient baselayer in cold conditions, yet our professionals never hesitate to use it as a high-performance t-shirt during the summer months as well. Pure comfort, every time you step out the door.

3D THERMO ULTRALIGHT
A 3D knit creates a thermal mattress made of ventilation channels and air cushions. It prevents direct contact with the skin and controls temperature variations between surrounding air and the skin. Body temperature stays at its normal internal level, 36-37.5°, so that the organism functions correctly.
