This custom hose / tubing cover is designed exclusively for use with ResMed's SlimLine and ClimateLine tubing. The Tubing Wrap will help insulate the hose from cooler outside air. In addition it improves the overall feel and look of the CPAP/BiLevel tubing on the bed. This Tubing Wrap is made of gray insulated nylon material and includes a zipper along the length of the wrap making it easy to attach and remove.
