Hot tubs are wonderful. The unspoiled outdoors is great. Dragging a traditional hot tub — and a generator powerful to run it — out into the wilderness? A complete PITA. The Nomad Collapsible Hot Tub lets you enjoy the bubbly goodness of a hot tub anywhere you like, thanks to a collapsible design that weighs just 20 pounds and can be filled in as little as 10 minutes. It offers a diameter of 60 inches, or enough room for you and a couple of friends, and is available in your choice of red, yellow, or black.
