Part of our Aerolite Collection, the Blizzard System now features an upgraded synthetic insulation that uses trapped air to replicate the warmth and compressibility of down. With this insulation, we’re able to add warm-when-wet performance — plus significantly reduce bulk — so you’ll be comfortable and mobile in a whiteout.
Taking cues from one of nature’s most effective insulators — trapped air — we saw an opportunity to make synthetic insulation lighter and warmer while keeping its warm-when-wet properties.
Aerogel, a material originally developed by NASA for use in aerospace applications, is composed of more than 95% air and is the lightest solid material known to humankind.
Tiny particles of infused aerogel form a temperature barrier to block out cold while the synthetic insulation traps air to keep you warm.
Aerogel is the world’s lowest density solid and most effective thermal insulator.
Synthetic PrimaLoft® Gold Insulation fibers are infused with tiny particles of aerogel that form a temperature barrier to block cold while the fibers trap air to keep you warm.
Made from 35% percent recycled material.
Like down, it’s highly compressible.
Unlike down insulation, it retains much of its insulating ability when compressed, and maintains its loft, even after years of packing.
Synthetic PrimaLoft® Gold Insulation with Cross Core™ technology replicates the warmth and compressibility of down...
But with the benefit of warm-when-wet performance.
