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 boy’s 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.
