Meron IN Hooded Jacket Men

Mammut themselves recommend the Mammut Meron IN Hooded Jacket for via ferrata, and the build does support this; with an adjustable helmet-compatible hood and raised pockets suitable for use whilst wearing a harness. The waistline is also adjustable, not to mention the elasticated cuffs, meaning that the jacket will sit nicely on the body. The Meron IN also has an element of water repellency, giving you the time to stow it away without ruining the fill.

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.
