Luft Pullover
The Luft technical down pullover is astonishingly light at 172g (size M) and packs down into its own pocket to 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 long 2-way 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.
