3-layer shell jacket engineered specifically for on-piste skiing.

The 3L Shell Jacket Prototype is a technical shell jacket designed from the ground up for skiing on piste, not adapted from outdoor or alpine shell concepts.
Built with 3-layer PFC-free polyester fabric and a DEFEND 4-way stretch membrane, this shell jacket delivers 20K waterproofing and 20K breathability, ensuring protection from snow, wind, and harsh winter conditions.
Its cut, construction, and functionality are developed to support dynamic skiing, movement, and long days on snow.

Fully seam taped construction, underarm ventilation, and waterproof reverse zippers enhance weather protection and thermal regulation.
Multi-functional internal and external pockets, an adjustable hood, and adjustable hem complete a shell jacket designed for precision, control, and performance on piste.
