The Adams is my favorite Jacket from Foursquare. The wrist gaiters that are found on this as well as other jackets in the Foursquare line are the best on the market. They have little pockets for a handwarmer that keeps you whole upper body nice and warm. The 15K shell is great protection against the elements that Utah's winters have to offer. The Adams jacket has a removable powder skirt and a removable hood. Great 2L shell jacket.
