Defying harsh winter conditions and enabling dynamic movements were primary considerations when Helly Hansen designed the women’s Enigma Jacket. Down insulation and PrimaLoft Infinity provide warmth and comfort inside; harsh winter elements are thwarted by Helly Tech Professional hard shell protection outside. Goose down separated by air channels on the jacket's interior backside trap warmth while the channels facilitate warm air circulation. Front and back ventilation zippers adjust how much warm air is trapped in the jacket and how much outside air enters for cooling. Additional features include a detachable and adjustable hood, RECCO reflector, articulated arms and elbows and zip-away powder skirt.
