Mammut says:

Warm insulated jacket: the Meron IN Hooded Jacket Men. Made from extremely light, polyamide ripstop material that reliably repels water. Various features such as a helmet-compatible hood as well as backpack- and climbing harness-compatible pockets make this jacket perfect for mountaineers. The 95% goose down and 5% feather filling keeps you warm in cold temperatures and has an excellent heat/weight ratio. Practical: stowable in the internal pocket.
