PrimaLoft is incredibly soft, lightweight, and breathable with excellent water repellency so you remain dry, warm, and comfortable, even under the most extreme conditions.
Ounce for ounce as warm as down, Primaloft microfibres are similar in size and shape to down, resulting in nearly equal insulating performance when dry and even better when wet. Because its individual fibers are water-repellent, Primaloft retains much of its ability to keep you warm, even when moisture has soaked through.
