Climashield™ Prism

Climashield™ Prism is Neo's genetic cousin and exhibits many of the same ultra-high performance qualities. Prism requires less wattage (i.e. energy) than any other fill, meaning that bags with Prism will maintain their temperature more easily when wet. Overall, Prism loses 15 percent less heat when wet.

Vaulted Footbox

The North Face®  innovative vaulted footbox provides sufficient space to allow the feet to flex and move naturally. This eliminates dead air space and keeps feet warmer and more comfortable.
