Taking cues from jackets designed with our pro team-looking Longo's direction-the Stone.91 Insulated Jacket packs big style and tech in a smaller package. A V-Science 2-Layer Supreme Twill outer is bolstered by 150/80g insulation and critically taped seams. Technical features like Zip Tech jacket-to-pant interface, a helmet-compatible hood with internal elastic gaiter, and a pass pocket with leash take this jacket to the next level of performance, but it doesn't stop there. Grow Tech extends the jacket's lifespan by quite literally extending the jacket.
