Pros and things to consider

Pros

• The 3-layer GORE-TEX is a waterproof, breathable and windproof material.
• It has a helmet-compatible hood and harness-compatible front pockets.
• The three-dimensionally cut sleeves and the adjustable cuffs and hem make it easy to fit to your body.

Things to consider

• It has no insulation, so on cold days you adjust by layering a midlayer underneath.
• It is built for overnight trips and technical routes, so using it only as everyday wear in town tends to leave its features underused.
• Sizes are European and run one size smaller than Japanese sizing (EU S ≈ Japanese M).

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. Is it compatible with helmets and harnesses?

A. The hood is listed as helmet-compatible and the front pockets as compatible with a climbing harness. How the hood fits over the helmet may vary depending on the helmet's shape.
