We received our snow tubes and immediately went 'sledding' the following Saturday. Boy, did we have fun! The tubes are made of thick vinyl and worth the money. Believe it or not, the tube is made for two people comfortably but we tried three people and it worked fine. We bought two of these for our grandchildren and they love them; so we keep one at our house and one at their house so they can have fun with mommy and daddy too. A great buy and lots of fun! I looked at other places but the prices were higher and the shipping was much higher because of the weight of the tube. In all, this is a great buy. Make sure you are ready to blow these up, better yet use a tube inflator if you have one. They are big.
