Hard Bottom Snow Tube
There are endless options out there for cheap plastic blow-up snow tubes. Most of them are goofy looking and all of them have a pretty short lifespan. We knew there had to be something better.
With a little searching, we found this Canadian maker of snow tubes who most often supplies commercial tubing operations (yay, high quality!). These tubes come in multiple sizes, include a heavy-duty lead and handles, have the option for a foam insert for butt comfort, and can be linked together for even more fun.
Also, it's constructed of an inner tube and outer cover, so if the rubber tube does fail, you can easily get a replacement tube at a much lower cost and keep using the original cover.
