I wanted to replace a second layar for something lighter.

Rating: rated 5 of 5 stars


I wanted to replace a second layar for something lighter. Very warm for its size. Packs into its own pocket.


  • Light
  • Warm
  • Packs into pocket

The fit is very good. I´m 5'4" and Small fits perfect. Still have space for one layer under and a hardshell over.  

Seems to have few down but still it's very warm. Very packable and compressible. Only has two pockets but is just what I was loocking for, something light. Has two drawcords for waist adjustment.

The construction has a very good finishing. Haven't tested it outdoors but will soon.
