FAQ

Q. How should I choose a size?

A. Mammut clothing uses European sizing. Asian Fit models (cut for Japanese body shapes, with sleeve and body lengths adjusted) run one size smaller than Japanese sizing.

M is equivalent to Japanese L, and the guide is a height of 172–178 cm and a chest circumference of 93–99 cm. The figures are approximate, based on the manufacturer's size guide.

Q. Can I use it with a helmet and a harness?

A. The hood is helmet-compatible, and the side zip pockets are designed with use alongside a climbing harness in mind. How the hood fits over the helmet may vary depending on the helmet's shape.
