A technology based on a special fibre construction that is responsible for thermal insulation and moisture wicking. It consists of an inner hydrophobic layer and another layer, the hydrophilic layer. The hydrophobic properties mean that the material does not absorb perspiration, but carries it away to the hydrophilic layer, where the perspiration is absorbed. The very lightweight LIFA® fibres are ideal for thermoactive clothing.

Using the properties of Merino wool, combined with KASK's exclusive helmet technology, the inner liner provides comfort without precedent. The natural fibres of Merino wool, when in contact with the skin, regulate body temperature, guarantee excellent air permeability and speed drying.
