The Sass’N’Frass Insulated Jacket delivers understated grown-up style in a smaller package. A V-Science 2-Layer Supreme Twill outer is bolstered by 120/80g insulation, a moisture-wicking Tafetta lining, and critically taped seams. Technical features like Zip Tech jacket-to-pant interface, Super Suede guard, and a pass pocket with leash take this girl’s jacket to a supreme level of performance, but it doesn’t stop there. Grow Tech extends the jacket’s lifespan by quite literally extending the jacket.
