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. S is equivalent to Japanese M, and the guide is a height of 167–173 cm and a chest circumference of 89–95 cm. M is equivalent to Japanese L, and the guide is a height of 172–178 cm and a chest circumference of 93–99 cm. L is equivalent to Japanese XL, and the guide is a height of 177–183 cm and a chest circumference of 97–103 cm. The figures are approximate, based on the manufacturer's size guide.

Q. What are the waterproofing and breathability figures?

A. The waterproof rating is 28,000 mm, and the RET value, a guide to breathability, is under 13 m² Pa/W. The lower the RET value, the more easily moisture escapes.

Q. Are there any features for ventilation?

A. There are 2-way zippers under the arms that you can open for better airflow.
