Snuggle Skins Insulating CPAP Hose Cover - Beige, Camel, Light Brown for 6' & 8' Hoses
Snuggle Skins are soft, washable fleece covers that help insulate your CPAP or BiPAP tubing.  They will decrease or eliminate the water condensating in your tubing (rainout).  Snuggle Skins are 9 feet long which not only provides extra insulation, but makes them able to fit either a 6 foot or an 8 foot long hose.  (You will need 2 Snuggle Skins if you have a 10 foot long hose.)
