In 1983, the US army asked PrimaLoft® to create a water-resistant alternative to goose down, so the troops could perform at their best, even when wet. Over thirty years later, PrimaLoft® is the industry-leader in synthetic insulation. Not only is it the highest performing insulation on the outdoor clothing market, PrimaLoft® offers a range of sustainable paddings that are made from post-consumer recycled materials. And thats just two of the reasons why Musto chooses PrimaLoft®.
