First impression
The Insuloft Superligt PL is really light, minimalist and very compact. When compressed, it takes up significantly less space than a 1 litre drinking bottle. This is partly due to the use of very high-quality materials, but also because it is a relatively thin insulating jacket. The jacket is basically designed as a mid-layer and therefore has a rather close-fitting cut, but it can also be worn as an outer layer over a jacket that is also rather close-fitting, such as a softshell.
Tester & test conditions
I am 183cm tall and weigh just under 80kg, I wear the jacket in size L, which fits me well. I ski a lot, mostly on ski tours. I had the jacket with me on several ski tours, but also in different conditions in the ski resort, both on and in my backpack.
