Assos Ultraz Winter Skin Layer P1 base layer

Your 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. Thanks to the highly insulating and elastic merino wool and synthetic fibre blend with which it is made, Ultraz P1 is our warmest first layer, complemented by the collar's neckwarmer structure that allows for extended protection. Unlike pure wool, its ultra-soft fabric does not cause irritation, while its high elasticity ensures that it never loses its shape even when stretched. What's more, this model moves with the body, offering a low bulk fit and adherence like a second skin that retains warmth and allows sweat to breathe, fundamental properties for ensuring maximum comfort during the coldest days of winter.

Technical features

First warmest layer fabric
Ultra-breathable, ultra-soft and incorporates carbon fibres to ensure constant odorControl properties. Synthetic materials provide high elasticity, while wool adds its natural antimicrobial and thermoregulating pro

Fit
Fitting the body like a second skin allows the fabric to remain in constant contact, maximising its thermoregulating properties and providing sweat management and breathability, for skin that is always warm and dry. It is also made from a single cut of fabric, removing the need to insert seams and thus causing potential chafing.

OdorControl
The Ultraz model is characterised by a higher carbon content and the natural antimicrobial properties of merino wool, ensuring a permanent OdorControl effect.
