Lifaloft™ is an insulation revolution that will keep you warmer with less weight and bulk due to the unique lifa yarn technology. Developed in cooperation with PrimaLoft®, Lifaloft™ is a combination of Lifa® and PrimaLoft® extensive knowledge in synthetic insulation. Lifaloft™ insulation is based on a yarn technology that traps more air vs polyester at a lighter weight. The fiber doesn´t absorbs water and has inherit water repellency without the need for treatment due to the hydrophobic properties of the Lifa® fibers which makes this insulation technology ideally for year around adventures in any condition and keeps you warm even when wet. Less carbon and water footprint vs comparable polyester for a lower environmental impact.
