PrimaLoft® Gold insulation with Cross Core™

PrimaLoft® Gold insulation with Cross Core™ technology fuses NASA developed Aerogel particles (composed of 95% air) with the superior warmth and packability of PrimaLoft® Gold fibers. Reaching new levels of warmth this insulation provides in excess of 50% more warmth compared to traditional PrimaLoft® Gold Insulation.

Extremely light, water repellent, breathable and compressible, PrimaLoft® was originally developed by the US Army to replace natural down in sleeping bags and coats that would get cold when wet. Forming tiny air pockets that trap body heat, it blocks the elements from the outside while still allowing moisture vapor from sweat to pass through, making it the go-to choice for adventurers needing protection in extreme conditions.

Their most advanced insulation starts with their best product, PrimaLoft® Gold, and utilizes NASA developed Aerogel particles, fusing them to the insulation fibers, creating PrimaLoft® Gold with Cross Core™. Composed of more than 95% air, Aerogel is the lightest solid material known to man and one of the most effective insulation materials, most notably known for its use in space suits. Providing 52% more warmth compared to traditional PrimaLoft® Gold Insulation, it not only leads the market in warmth-to-weight ratio, but is also made from 90% recycled material and is Bluesign® approved.

How is Aerogel made? NASA explains it best

“Picture preparing a bowl full of gelatin dessert. The gelatin powder is mixed with hot water, and then the mixture is cooled in a refrigerator until it sets. It is now a gel. If that wiggly gel were placed in an oven and all of the moisture dried out of it, all that would be left would be a pile of powder. But imagine if the dried gelatin maintained its shape, even after the liquid had been removed. The structure of the gel would remain, but it would be extremely light due to low density. This is precisely how aerogels are made.” - NASA

Paired with our air-permeable, weather resistant Recon face fabrics, our line featuring PrimaLoft® Cross Core™ technology is as good as it gets when it comes to staying warm and dry.
