The PolarShift4 features two separate sections, allowing you to fill one side with cold water and other with warm water. This is a convenient way to achieve contrast bath therapy by alternating between the two, as well as accommodating two people at once.
The PolarShift has all the necessary connections to attach a ReGen8 chiller unit or jet heater. You can purchase these separately or as part of a bundle.
Unlike bulky, traditional ice baths, the PolarShift4 is designed for an effortless setup and transport, inflating in 5 minutes with the included hand pump.
The unique "slipper tub" shape is ergonomically sloped on one side, providing the perfect angle for you to rest and lie back comfortably.
The large side-by-side tubs allow for full body extension and immersing yourself completely.
*Depending on the user's size and body position, the average usable capacity will be <1000L.
Tough PVC with Rip Stop fabric is both rugged and flexible, offering the resilience to handle the demanding environment of cold plunges while maintaining its shape and strength over time.
Included in the package are a hand pump, carry bag, repair kits (featuring repair patches, air valve wrench and water port plugs), so you won't have to worry about a thing.
Contrast therapy is the practice of alternating between hot and cold environments, such as going into a sauna after a cold plunge. The process of cooling then rewarming your body stimulates blood flow and improves circulation. The PolarShift creates a convenient form of contrast therapy by having two separate, side-by-side sections of different temperatures you can alternate between.

Regular cold plunges can boost immune function by increasing white blood cell production.
Exposure to cold activates brown fat, which can help burn calories and regulate body temperature.
Cold therapy naturally lowers cortisol levels.
