PrimaLoft
Cross Core platform integrates aerogel in fibers

The insulation will contain up to 90% recycled product content, while maintaining their performance attributes.
The series now includes a stretch version for freedom of movement. The Cross Core platform fuses existing PrimaLoft fibers with next-generation materials. The current products in the PrimaLoft Cross Core Series utilize Aerogel for increased thermal performance. Originally developed by NASA, it is used in aeronautical applications. Silica aerogel is composed of more than 95% air and is the lightest known solid material, and one of the most effective insulation materials.
