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 虂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.
