This insulation jacket combines a PERTEX QUANTUM Diamond Fuse shell — an ultralight, high-density recycled nylon certified to bluesign® and Global Recycled Standard — with 40g PrimaLoft Gold insulation that retains warmth even when wet. A Toray AIRTASTIC 10D lining suppresses loft bleed and delivers a smooth next-to-skin feel, while underarm fleece panels vent excess heat during active use. The stand collar with a concealed front zip and internal stretch tape at the cuffs and hem create a clean, refined silhouette that seals out drafts without restricting movement.
