PureSom Ruby FIXED SIZE Chinstrap for CPAP & BiPAP Therapy

The Ruby Chinstrap's ultra wide bands and unique, continuous flow design provide greater stability with less slippage than many other chin straps. Because the Ruby FIXED SIZE Chin Strap comes in three sizes there is no need for constant adjustment; instead you get a perfect, comfortable fit all night every night.

The Ruby Fixed Size Chin Strap helps hold the mouth closed during CPAP and BiPAP therapy. It is an ideal accessory for users who find that they lose therapy air because their mouth hangs open during sleep.
