Helly Hansen has developed a new entry-level type of insulation together with Primaloft, called Warm Core, for which it will have exclusive use for the first year. In the context of this arrangement, Helly Hansen has decided to use only Primaloft for insulation purposes in its entire fall/winter 2011-12 product line – outdoor, winter sports, sportswear and kids. Helly Hansen had used other types of insulation before. It will continue to use its own waterproof and breathable membranes.
