The Boulder Gear Women's Brio Snow Jacket was engineered for winter! The shell fabric has a waterproof/breathability rating of 15k with critically sealed seams to keep you dry in the elements. It has 120g polyester insulation in the body and sleeves and 60g in the collar and hood to keep you warm. Thick oversized drawcords help you keep out the chill and side ventilation allows you to shed excess heat. The attached hood gives you added coverage and the SAB® 2 way zipper makes zipping in easy.
