Primaloft Infinity

Primaloft Infinity is a lightweight, high loft, synthetic insulation that uses a continuous filament, as opposed to many separate small bits of fiber, which allows for better compressibility compared to other synthetic insulations.

PrimaLoft Infinity is also highly water resistant so, unlike other natural insulators like down, PrimaLoft Infinity can still insulate even if it gets wet.

This high loft continuous fiber forms many micro air pockets between layers that trap the heat from your body and keep out cold air. This method allows for optimal warmth to weight ratio.
