The Q36.5 Intimo Teddy Berry base layer is the answer to the extra warm request for coldest conditions. 

A result of development in cooperation with UVU (specialists in UltraRunning) and tests in Arctic conditions during an Ultra-running marathon. With a new concept of performing base layer extra thermal capabilities and a 3D structure, not your typical or traditional sport base layer. Following the principle of RSR (Regional Sweat Rating), for a body mapping calibrated to the needs of athletes, the Teddy Berry is constructed with a double frontal layer, for a better thermal protection during activity.
