PSOLAR.EX has been in business since 2002. Psolar.Ex is famous for it's heated face mask. The masks are made with the QXtec technology. This technology was invented by Lee Bagby, a professional mechanical engineer. Bagby is an avid outdoor enthusiast and enjoys cold weather activities. PSOLAR.EX has three partners, all of whom are mechanical engineers. The Patent Pending mask features a QXtec module that is made of desiccant coated plastic. The desiccant grabs the moisture from the air, forcing a phase change from vapor to liquid. This phase change releases heat that is added to the natural heat of exhalation, warming the plastic. This warmth is transferred to the air as it is inhaled - creating a warm “breath of sunshine.” The heat exchanger is up to 80% efficient, meaning that at 0 Degrees, your inhaled breath can be warmed to over 75 Degrees before it enters your body! Efficiencies vary with respiratory rates and lung capacity
