If you sleep on a water-cooled mattress pad, you know the hose is the weak spot. Run it under the mattress or behind the bedhead and it pushes against your fitted sheet all night, lifting the elastic and pulling a corner loose by morning.
HydroClip™ solves it at the source. A full-height opening in the side skirt, closed by a YKK® clip built into the elastic, lets the hose exit through the side of the bed. The elastic stays tensioned, the corners stay put, and you can change the bedding without disconnecting the hose.
One set, two pieces: a waterproof mattress protector and a fitted sheet, both in ultra-thin Austrian Tencel™ eucalyptus and both with the HydroClip™ opening built in. Designed for the Oak Sleep HUB 2, Eight Sleep and Chilipad.
The hose exits the side, not underneath
Clip ports sit on the left side and centred at the head or foot (Super King has three), so there's always an exit facing your hub or wall outlet. The opening runs the full height of the skirt, so the tube can leave at mattress level or anywhere below.
Change the bed with the water still running
Release the clip and the sheet comes away around the connected hose. No draining, no disconnecting, no re-priming your system. A full bed change takes about 30 seconds.
Thin enough to let your pad do its job
Thick cotton and polyester act like insulation between you and your cooling pad. This 300TC eucalyptus is one of the thinnest natural-fibre sheets around, so heat and cool pass straight through and your system holds its set temperature more easily. Oak Sleep has tested it with Eight Sleep and other sensor-equipped pads, and sleep tracking keeps reading as normal.
Natural fibre, nothing synthetic against your skin
100% Austrian Tencel™ eucalyptus from Lenzing, OEKO-TEX® Standard 100 certified, from FSC® and PEFC™ certified forestry. No polyester, no microplastics, minimal bleaching. The protector uses a breathable TPU membrane, not vinyl.
