Edge Theory Labs
The cold plunge that packs into a duffel.
What they're known for
An inflatable tub and a portable chiller — pro-team cold immersion that moves with you.
Edge Theory Labs solved the cold plunge's real estate problem. The Edge Tub is a heavy-duty inflatable vessel paired with a portable chiller that pulls water down to plunge temperature — the whole system packs into bags, travels to a competition or a backyard, and sets up in under an hour. Pro teams adopted it for exactly that reason: real cold immersion that doesn't live anywhere permanently.
The honest trade against a steel tank is permanence and polish; the win is that this is the serious plunge for renters, travelers, and anyone not ready to commit a patio corner forever. Chiller-cooled, filtered, and genuinely portable is a combination nobody else nailed first.
