It’s amazing that we don’t see more surfers-turned-serial killers. Think about it: Mother Nature restricts them – especially those who live in the Northeast — from their passion for 5 or 6 or 7 months a time. It’s gotta be frustrating. The Surf Sauna is the kind of solution that virtually guarantees we’ll never see Kelly Slater snap, as this portable hothouse keeps you warm in even the dreariest of winters. Like say, this one, for example.

Each Surf Sauna is built to the buyer’s specifications, fitting anywhere from 2 to 8 people. It can be outfitted for off-road conditions, and basically customized however you like by the builders in New England who invented it out of necessity. Pony up $18,000 and you’re set, or go the thrifty route and rent it for the day. [Purchase]
