Features a unique glider mechanism that eliminates side-to-side leaks by allowing the headgear to move freely while the mask cushion stays in place. The redesigned T piece has an optional locking position, which reduces pressure on the bridge of the nose. The foam and silicone seal deliver unmatched comfort. The diffuser removes draft and helps make the Aclaim 2 one of the quietest nasal masks on the market today. Breathoprene headgear has been added to keep the Aclaim 2 cool and lightweight when in use.
