At first glance, the Burton Hackett Jacket looks and feels like a heavy-duty workwear flannel. Dig deeper and you'll discover some serious cred like burly waterproof/breathability, high-loft, lightweight 3M™ Thinsulate™ Platinum Insulation and a fresh yet functional quilted satin lining. In the arm pits, X-STATIC® antimicrobial insulation provides stink protection. A stealth way to shed extra layers, this single piece consolidates flannel, puff and shell into one. Rider-ready, it contains all the necessary features—fully taped seams, a waist gaiter, and venting to battle everything from arctic temps to springtime slop.
