Helly Hansen Alpha 4.0 Jacket

HELLY TECH® Professional Waterproof & Breathable Protection

The Helly Hansen Alpha 4.0 Jacket is a flagship resort ski jacket engineered for skiers who demand reliable protection, warmth, and performance in all mountain conditions. Built with HELLY TECH® Professional fabric, it delivers fully waterproof, windproof, and breathable protection to keep you dry and comfortable throughout long days on the slopes.

Inside, PrimaLoft® insulation provides lightweight warmth with strategic body-mapping to retain heat where it’s needed most while maintaining mobility and breathability. The integrated H2Flow™ ventilation system allows for dynamic temperature regulation, helping you release excess heat during high-output activity or retain warmth in colder conditions.

Designed for resort performance, the Alpha 4.0 combines technical functionality with a refined athletic fit, making it suitable for skiing, riding, and all-day winter wear in demanding alpine environments.
