The Burton Men's Biggs Puffy Vest: mountain-incubated function combined with raw street style, this vest is no smalltime act. Plush tech performance stems from 3M™ Thinsulate™ Insulation sheltered within the water-repellent tech of a nylon twill fabric with DRYRIDE Mist-Defy. Custom design in every stitch with a flannel lining and unique fabrications to each colorway, its street fit blends from liftline to bar line and includes zippered handwarmer pockets, and custom logo details.
