Alpha 4.0 Ski Jacket

Helly Hansen’s best-selling men’s ski jacket. A consistently top-rated resort ski jacket in independent tests that sits one level below the Alpha Lifaloft in the range but offers a more versatile warmth profile for all-season resort use. The jacket uses HELLY TECH Professional 2-layer construction — the highest tier of Helly Hansen waterproofing — combined with body-mapped PrimaLoft BLACK Eco insulation (80g body, 60g sleeves) to provide warmth that is precisely calibrated to where the body needs it most.

The unique H2Flow system combines underarm ventilation zips with laser-cut mesh air ports at the back to create a dynamic temperature management system that retains heat or dumps it depending on exertion level — a feature that genuinely extends the jacket’s useful temperature range across a full ski season. A Life Pocket with Aerogel insulation protects phone battery life, and a detachable helmet-compatible hood, adjustable stretch powder skirt, neon brim and wrist gaiters complete the specification. Bluesign certified; contains recycled Ocean Bound plastics.
