Craig J.wrote a review of Arc'teryx Kappa AR Insulated Jacket - Men's on February 22, 2010
This jacket rocks. I can easily wear it in temps to 20 degrees or lower and not be chilled. I forgot my Arc'teryx Sidewinder hard shell on a recent ski outing and only had the Kappa. Thought I might be cold but was toasty warm all day even when the wind blew.
