Iving 3.0 is Klättermusen’s heavyweight expedition down jacket, first introduced in 1989 and rebuilt for Arctic exposure. Box-wall chambers surround 750+ fill-power down, while updated sleeves stabilise the fill to limit migration over extended use.
The fully taped shell exceeds a 20,000 mm water column and remains highly breathable. PrimaLoft supports pressure areas, and a thermally sealed front zip, padded storm flaps and reinforced sleeves control the vulnerable zones.
A 3D-adjustable down hood follows the head, with a wired Windvisor protecting sightlines. Generous storage and an alternate snap-and-toggle closure keep the system usable when deep cold makes every opening consequential.
