## Assos Ultraz 3/3 Face Mask P1

The Assos Ultraz 3/3 Face Mask P1 is a highly insulating **balaclava** for the coldest cycling days in Switzerland. Its focus lies on a **dual-layer construction** that retains heat and reliably wicks moisture away from your head, keeping you dry even in strong winds and sub-zero temperatures. Compared to the previous model, breathability has been increased and drying time reduced, which is a noticeable advantage especially on long winter rides. The **seamless**, pre-shaped fit sits comfortably and disappears easily under your helmet and jacket without creating pressure points.

- **Dual-layer insulation** for maximum warmth in deep winter
- **Seamless** construction and pre-shaped pattern for pressure-free comfort
- **odorControl** with permanent antimicrobial properties
- **Helmet-compatible** low-profile fit, quick-drying
- Material blend: 83% **polypropylene (PP)**, 9% polyamide, 8% elastane
- Also available as single-layer alternative: **Winter Face Mask P1** (less insulation)

## Technical Details and Features

The Ultraz 3/3 Face Mask P1 uses a **dual-layer** textile combination: an inner, warming layer is protected by an outer layer, creating a dry, warm microclimate. The fabric is soft, highly elastic and **pre-shaped**, so it closely wraps around head, face and neck without restricting freedom of movement. The **seamless construction** reduces friction points, which is particularly important when layering under a helmet. The material setup consists of 83% **PP**, 9% PA and 8% EA – chosen for efficient moisture management and quick drying when performance increases. Within the Assos system, **3/3** marks the winter level, meaning the highest warmth classification for extremely cold conditions. In earlier Ultraz generations, this dual-layer concept was called twinDeck – a good indication of the technical DNA behind the current P1 version.

## Applications and Benefits

This mask is the right choice for **commuters** in Zurich, training rides around Lake Greifensee or alpine winter tours when cold, wind and moisture combine. Thanks to its **low-profile** fit, it fits under any road bike or MTB helmet and overlaps cleanly with winter jackets and neck areas, preventing cold bridges. Its higher **breathability** prevents moisture buildup that could cool you down when you push hard on climbs or pause briefly at traffic lights. If you need less insulation, go for the single-layer **Winter Face Mask P1**; for real cold days, the Ultraz P1 offers the noticeably warmer option in the Assos range. Even within the context of the Assos winter line, "Ultraz" stands for the warmest setups – a classification reflected in independent tests of the Ultraz winter clothing lines.

Additional Notes on Fit and Care

Assos offers the Ultraz 3/3 Face Mask P1 in **size III**, which thanks to high elasticity covers a wide range of head circumferences and fits snugly but comfortably. The **seamless** construction minimizes pressure points, which is particularly noticeable on longer rides with lots of layering. The **odorControl** treatment remains effective even after washing, keeping the mask fresh longer and requiring less frequent intensive cleaning. For care, we recommend a gentle wash cycle with mild detergent and air drying to permanently maintain elasticity and shape.
