Versatile, packable, insulated warmth. The men's Rossignol Opside Hoodie Jacket is a warm, technical midlayer under your shell on a cold day at the mountain and a standalone, wind-resistant layer for a day hike or trail run in cool weather. PrimaLoft® insulation, along with details like an integrated hood, elastic cuffs and an adjustable hem, offer all-conditions warmth without adding bulk.
