There is only one way to really understand what men's Outright Pants are all about. Try them on. The secret is called Power Stretch ProLight, a stretchy fleece fabric that will keep you warm and pull moisture away from the skin. The technical fabric makes the men's Outright Pants great for layering in really cold weather. They are light and breathable enough to wear under a pair of shell pants in the ski slopes. The fabric has a smooth, durable outside and a soft, fuzzy inside. Technical properties aside, most of Houdinis customers simply enjoy the comfort of the men's Outright Pants with a cup of coffee in front of the fireplace. If you are looking for a pair of warm, light and stretchy fleece pants this is your match. A little warning though, once you put them on, you will never want to wear any other pants.
