Built for the most demanding site conditions, the Helly Hansen Magni Evolution Winter Jacket is serious cold-weather workwear engineered around Helly Hansen's own HELLY TECH® PROFESSIONAL waterproof and breathable membrane. With a 20,000mm waterproof rating and 15,000g breathability, it shrugs off the worst that British winters throw at a working trades professional. The 2-way stretch recycled polyamide shell moves with you rather than against you, and PrimaLoft® BLACK Eco insulation keeps the heat in during the cold moments while the H2FLOW™ ventilation system lets the heat out when the work heats up.
