The Alpha 3L Long Shell is resort-ready with a long list of features and Helly Hansen technologies to perform on the mountainside. With 4-way stretch and 3-layer construction, the Helly Tech Professional Shell preserves our freedom of movement while protecting us from the elements with its durable and breathable waterproofing. The Alpha is stacked with several ski-specific pockets, inside and outside, to organize our kit, and its side ventilation openings keep us from overheating when we're sizzling on our skis.
