Foursquare didn't mess around with the Women's Bevel Pants. These things pack a waterproof breathable shell with full seam tapping and light insulation. Basically, all you need for a day of nasty weather. Powder day's don't happen under bluebird skies, so you want to be ready with something that's going to get you through the blower without getting soaked. Foursquare included thigh venting to help you cool off when the skies to clear, so you can rip from first chair to last without stopping to change.
