Technologies:

Lifa: Launched in the 1970s and improved over time, Lifa is a hydrophobic fiber that provides insulation and moisture management. It moves sweat away from the skin and to the surface of the fabric, where it evaporates. Lifa fibers are used in the first layer of base layer garments, the one closest to the skin. This layer, made of Merino wool, is combined with an additional layer of hydrophilic (moisture-wicking) material so that sweat is moved away from the skin and transported to the second layer, where it is absorbed. This allows the wearer to stay warm, dry and comfortable. Lifa fabric is ultra-lightweight.

LIFA Merino: A unique 2-in-1 base layer that combines lightweight LIFA fibres next to the skin and an extremely soft Merino wool outer. It is Helly Hansen's warmest base layer and is recommended for any type of outdoor activity in winter.
