The windproof and waterproof 3-layer GORE-TEX® with C-Knit lining technology makes this coat from our urban Mammut-Delta-X collection suitable for all weathers. The hard shell jacket features a design based on the Georganic Y-shape. Tailored to natural movements, this construction provides optimum freedom of movement.

Performance meets design

Clearly defined lines, taped seams and a streamlined shape. The 3850 coat combines design with functional technology for an urban look.

Comfortable to wear

Gore-Tex with C-Knit lining technology stops water from penetrating while allowing vapor to wick to the outside. This ensures a comfortable feeling in the 3850 HS Coat.
