When you're out camping, roughin' it in the woods, sometimes you crave a little luxury. Luckily, The Original Nomad, a company specializing in outdoor products, has come up with a pretty awesome item that will make your camping trips 100x better. The Nomad's Collapsible Tub is a hot tub you can take with you anywhere you go. It can easily be set up and stowed away in no time, making it super convenient.
It uses a water heater coil to get the water hot. Firewood will help get the heater going, but you can also use propane.
It takes a little while to warm up (around 2.5 hours to get to 105° when it's 60-70° out) but it's well worth the wait.
It's plenty big for a good group of friends.
