the Kenai, both hooded and non-hooded, is my favorite piece of kuiu gear after the attack pants. I run hot with very little exertion and this allows you to wick sweat while actively hiking in cold conditions. It will allow your base layers to dry as well, wicking sweat through the kenai. Often I can get away with only wearing the kenai for cold weather, but will bring the super down LT or super down pro as a backup for severe cold since it's so lightweight. The Kenai is money!
