Product details:

LIFALOFT is a revolutionary insulation technology that will keep you warm with less weight and bulk. After four years of development and thanks to collaboration with the Swedish Ski Team, LIFALOFT has a 20% lighter warmth to weight ratio than comparable products. By combining Primaloft's extensive knowledge in synthetic insulation with our exclusive LIFA fiber technology, LIFALOFT traps a maximum amount of air in a small space; making it warm, lightweight, and low-profile. Plus, due to the hydrophobic properties of LIFA, LIFALOFT has an inherent water repellency that will keep you warm, even when wet. It's perfect for year-round adventures in all conditions.
