Küki Jacket

*New Production Available March '26* As light as "air" [Küki in Japanese] at 172g/6oz (size M) and packs down into the size of a water bottle. Designed primarily to serve two purposes; as a stand-alone “sweater” when lightweight and packability is the goal such as long distance & duration runs/hikes/bikes and as a perfect mid-layer under a shell when a normal puffer/down jacket is too much. A full length center zip provides many ventilation options. 

A casual “sweatshirt” fit slides easily over a tee-shirt or base layer. Wear it around the house when your partner won’t turn up the heat.

At elevations above 5,000 feet, down insulation is a year-round thing. In our home state of Montana summer temperature swings can toggle between 80°F days to 30°F nights. A microlight down layer, that can be deployed on a moment's notice becomes an everyday staple.
