About the Brands
HigherDose
HigherDose's sauna blanket is a zip-up, mat-style infrared unit that heats the body directly rather than the surrounding air, positioned as a lower-cost, no-installation alternative to a cabin sauna.
Full profile →Plunge
Plunge's tubs hold a set temperature automatically via a built-in chiller unit rather than requiring ice, with ozone-based filtration to reduce how often the water needs to be changed.
