The warmest essential base layer for particularly cold, extremely harsh winter weather, optimized with an ultra-high collar, additional odorControl and a highly elastic wool blend for insulation close to the body.
Thanks to merino wool and a highly elastic, highly insulating material blend, this layer offers the best insulation of all Assos skin layers, while an updated collar construction that can be used as a turtleneck further extends its functionality. Unlike pure wool, the ultra-soft textile is not irritating and thanks to its high elasticity, it does not lose its shape when stretched. Instead, it follows the body's movements and fits close to the skin with little bulk to trap heat and wick away moisture - both of which are crucial for comfort in the depths of winter.
