Helly Hansen Alpha 4.0 Jacket

Technical ski jacket with innovative insulation, maximum freedom of movement, and practical features for skiing.

The Men's Alpha 4.0 ski jacket from Helly Hansen is the ideal companion for discerning skiers who don't want to compromise on comfort and functionality, even in extreme conditions. Equipped with the proven HELLY TECH® Professional technology, the jacket offers reliable protection against wind and water while remaining breathable. The PrimaLoft® Black Eco insulation ensures comfortable warmth thanks to intelligent body mapping, while the H2Flow™ system optimally regulates body temperature through mechanical ventilation.
The jacket stands out for its well-thought-out and articulated cut, which allows for maximum freedom of movement on the slopes. Practical features such as a removable, helmet-compatible hood, an adjustable snow skirt, and a neon-colored brim enhance its functionality. The ski pass pocket and the Life Pocket™, which protects your phone’s battery in cold weather, are additional thoughtful details that enhance comfort.
Fully taped seams, brushed side pockets, and an inner hanging loop round out the jacket’s well-thought-out design. The 4-way stretch fabric and adjustable cuffs with fasteners offer additional comfort and flexibility. This ski jacket is the perfect choice for anyone who values quality and thoughtful details so they can enjoy their day in the mountains to the fullest.

The essentials

A good fit if you want stretch fabric and pre-shaped sleeves while skiing
A good fit if you want an insulated jacket with ventilation you can open on the go
Less so if you want an uninsulated jacket for layering: the Alpha 4.0 has synthetic insulation.

What is it for?

Warmth

Lightly insulated

Our take

If you move a lot while skiing, the 4-way stretch fabric and pre-shaped sleeves give you room to move. H2Flow ventilation lets you regulate the temperature in the insulated jacket. You can wear the hood over your helmet or remove it.
