Ultraz Winter Face Mask

The Assos Ultraz Winter Face Mask is engineered for extreme winter cycling and is also suitable for skiing and snowboarding, with a low-volume shape that layers under helmets and tall jacket collars.

The mask is 40% nylon, 36% polypropylene, 15% elastane, and 9% polyester, and uses a twinDeck double-layer construction—Push Pull Medium exterior and Rhombus inner lining—to trap warmth while wicking and expelling moisture to the fabric surface.

It comes in sizes I and II with a pre-shaped, six-panel, low-volume fit that wraps closely around head, face, and neck for a pressure-free feel and seamless helmet integration; Size II weighs about 82 grams.

Yes, Push Pull Medium’s open knit and the Rhombus 3D diamond net interior promote airflow, faster drying, and moisture transport, and the fabric includes an odorControl antimicrobial treatment that persists through washing.
