KNOW YOUR TECH breaks down the scientific technology used in your favorite sneakers and activewear. Let’s demystify your next purchase: today’s technology is Primaloft. Straight from a manufacturer that specializes in insulation technology, Primaloft is used by a number of brands to provide water resistant thermal insulation. Whether it’s used in apparel, boots, or gloves, Primaloft synthetic construction allows for more practicality than traditional goose down fills.
What is it? Primaloft insulation is composed of ultra-fine microfibers, which form small pockets of air that trap the body’s heat for a climate-controlled environment. The fibers are built to be permanently water resistant, and have been woven tightly to keep moisture from penetrating the garments.
How does it work? Because the synthetic fibers of Primaloft One dries faster than goose down, it’s able to maintain its high levels of warmth and water resistance more efficiently than traditional fills. At the same time, it’s just as compressible as the insulation you’re used to.
Bottom line: Primaloft’s lightweight, yet insulated feel is sure to keep you warm and dry throughout winter.
