Thanks to its blend of merino wool and highly insulating and stretchy synthetic fibers, the Ultraz P1 is our warmest base layer, complemented by a neck warmer construction that extends its protection. Unlike pure wool, its ultra-soft fabric doesn't cause irritation, while its high elasticity ensures it never loses its shape even when stretched. Furthermore, this style moves with the body, offering a low-bulk, second-skin fit that retains heat and wicks away sweat—essential properties for maximum comfort during the coldest winter days.

The peculiarities

FEATURED FABRICS
Our warmest, ultra-breathable, ultra-soft base layer fabric, incorporating carbon fibers for consistent odor-control. Synthetic materials provide exceptional stretch, while wool adds natural antimicrobial and thermoregulating properties.

CONSTRUCTION/FIT
The second-skin fit allows the fabric to remain in constant contact with the body, maximizing its thermoregulating properties and providing sweat management and wicking, keeping skin warm and dry. It's also made from a single piece of fabric, eliminating the need for seams and potential chafing.

ENGINEERING
odorControl: The Ultraz model stands out for its higher carbon content and the natural antimicrobial properties of merino wool, ensuring a permanent odorControl effect.
