Unparalleled Comfort and Temperature Regulation

Crafted with 100% Merino wool or our innovative Intraknit™ technology for maximum durability, our base layers act like a second skin. Choose from:

• Classic Thermal Merino (Weight 250 g/m²): Our warmest base layer, ideal for activities in intense cold conditions (skiing, snowboarding, winter hiking). It offers excellent thermal insulation while maintaining crucial breathability.

• Classic All-Season Merino (Weight 150 g/m²): Lightweight and versatile, perfect for all-season activities. It regulates body temperature, keeping you cool when it's hot and insulated when it's cool.

• Intraknit™ Thermal Base Layers: These utilize 3D body mapping to offer targeted warmth and ventilation in the areas that need it most, with a seamless construction for superior freedom of movement.

• Intraknit™ Active: Designed for high-intensity activity, these base layers combine the softness of Merino with the durability of polyester, guaranteeing maximum breathability and ultra-fast drying.
