Description

The Helly Hansen Alpha 4.0 ski jacket is designed for passionate skiers and snowboarders. Built with a Helly Tech Performance 20K/20K membrane, it delivers outstanding waterproofness and breathability, while its durable water repellent finish (DWR) and waterproof seams further enhance its ability to withstand moisture. The four-layer construction ofhis ski jacket ensures effective thermal insulation thanks to the Primaloft Ocean Bound 80g fill. This insulation, combined with a membrane lining, provides optimal warmth and comfort. H²Flow ventilation channels promote airflow for excellent temperature regulation.

The adjustable snow skirt prevents powder from entering at the waist, while the adjustable and removable hood (helmet compatible) offers extra protection against harsh weather conditions. Articulated arms and elbows guarantee maximum freedom of movement. Finally, this model features a RECCO reflector for added safety when venturing off-piste.
