Mammut says:

Reach for the Masao Light HS Hooded Jacket when you hear the call of the mountains. The jacket’s waterproof outer material is complemented by waterproof zippers and a helmet-compatible hood to protect you from adverse weather. This hard shell jacket also features pre-shaped sleeves and hems that can be adjusted for an individual fit. The jacket impresses with its very small packing volume. It comes with a handy stow bag to allow you to carry it in your backpack in case of need. Pockets that you can reach even when wearing a climbing harness add the perfect finishing touch to your alpine experience.
