Are you talking about these?
Cause if you are they are expensive as shit. I used to be a lifeguard at a water park and one of them got a hole that we couldnt patch and we had to order a new one. Theyre not really available to the public either. Now the way I see it you have a few options for floating/rafting/river adventure (whatever the fuck you call it around there).
1. The classic River Rat. Cheap, portable, holds a cooler like a boss, round, floats.
2. The big O (screamer). Big, flat, fits two people, awesome to pass out on or fingerblast other river rats
3. Floating mat. Fun, different, bitches will think youre Jesus walking on water, expensive.
4. Canoe/Kayak. Youll be "that guy in a canoe", makes you look like a nickleback fan, endorsed by Hitler
