ABSTRACT:
A flexible mouth seal having a porous direct flow hygroscopic material associated with a cold weather mask. The nose has free breathing and does not breath in or out through the hygroscopic material. The cold weather mask and mouth seal captures some of the moisture in exhaled air by a porous hygroscopic material and returns the moisture to the dry cold inhaled air for assistance in cold weather breathing.
