Streamlined and stylish, the alpine inspired Sierra Jacket was designed for serious on-snow action. 4-way stretch shell fabric allows for maximum movement, while the (15,000mm/15,000g2) waterproof/breathability rating offers ultimate protection. Lined with Primaloft® Black Eco insulation providing superior warmth with none of the bulk. You can detach the faux fur or the entire hood for those warmer winter days. Underarm venting, internal powder skirt, and “soft-touch” wrists cuffs are just a few of the features integrated into this ultimate winter jacket.
