Insulation
We use PrimaLoft® insulation inside insulated garments for its warmth, compressibility, and soft comfort. While the human body uses energy to stay warm, PrimaLoft insulation uses a patented microfiber structure to help the body retain warmth and conserve energy.

The proprietary ultra-fine fibers of PrimaLoft insulation form a tight collection of air pockets that trap heat from your body and keep the cold out, providing an excellent warmth-to-weight ratio. When insulation gets wet, it loses these air pockets and consequently, its insulating properties. PrimaLoft ultra-fine fibers were developed to be water resistant so your insulation stays drier and maintains its insulating properties even when wet.

Fair Trade Certified™
We pay a premium for every Fair Trade Certified item that carries our label. That extra money goes directly to the workers at the factory, and they decide how to spend it. The program also promotes worker health and safety and social and environmental compliance, and encourages dialog between workers and management.
