A 750 fill power, ultra-compressible down jacket characterized by beautiful workmanship and attention to detail. A nice touch is the two-way zip, allowing easy access to a harness. Despite being lightweight, Mammut have not skimped on durability; the 30D Pertex Microlight shell feels tough and I like the taped backing to the zip baffle. The shell has a PFC free water repellent finish and on test, getting caught out in a light shower didn’t overly affect lofting, but Mammut don’t indicate that the down has any water repellant treatment, so its best suited to sub-freezing temperatures. Weight 380g.
