The Coolmax Thermo functional underwear range consists of a warm, single-ply elastic knit ideal for all winter chillers. The material used guarantees excellent functional properties, moisture transport away from the body and thermoregulation ability. The use of COOLMAX® Fresh fibre with permanently incorporated silver ions also brings high and lasting antibacterial properties. Thermo is durable, dimensionally stable and highly elastic, yet the linen is very soft to the touch. By intensive combing of the reverse side, the knit gains volume and softness. The underwear can be used as a first or second layer and is suitable for all-day wear, winter sports and leisure activities.
