Assos' warmest first layer, designed for the coldest temperatures and most extreme weather conditions and perfected with an ultra-high collar, additional odorControl properties and a highly elastic wool blend fabric to ensure thermal insulation that follows the lines of the body.
Made from a blend of merino wool and highly insulating, stretchy synthetic fibres, the Ultraz P1 is the warmest first layer, complemented by a neck warmer collar that extends the protection. Unlike pure wool, the ultra-soft fabric is irritation-free, while its high stretch ensures it never loses its shape even when stretched. Plus, it moves with your body, providing a low-bulk, second-skin fit that traps heat and wicks away sweat, essential for staying comfortable on the coldest winter days.
Fabrics : The warmest Assos first layer fabric, ultra-breathable, ultra-soft and integrating carbon fibers to ensure constant odorControl properties. Synthetic materials guarantee very high elasticity, while wool adds its natural antimicrobial and thermoregulating properties.
Construction : The second-skin fit allows the fabric to remain in constant contact, maximising its thermoregulating properties and offering sweat management and wicking, to always keep the skin warm and dry. It is also made from a single cut of fabric, removing the need for seams and thus causing potential chafing.
odorControl technology : The Ultraz model stands out for its higher carbon content and the natural antimicrobial properties of merino wool, ensuring a permanent odorControl effect.
