High-Flow Performance
The OG is built around stronger water movement than any plunge in its class. Our high-flow system continuously circulates the entire tub, keeping water colder, cleaner, and more consistent from edge to edge. This eliminates warm spots, improves immersion, and maintains water clarity with less effort.
When it comes to flow, the OG moves more water — and moves it better — than anything else in the category.
More flow means a better cold plunge.
