RIVER OTTER DELUXE River Tube

I live near a beautiful but obstacle-filled rocky river in the mountains that is very popular to float. Everyone buys the cheap plastic tubes that inevitably pop along the river (I used to be among them!). Then I bought these. VERY hardy (as other reviewers said). Have used four times now in late summer (when river is at its lowest AKA most obstacle-filled) and they've performed perfectly every time. Also, to the point others said about the tube cover being slow draining when you get out of the water: when I exit the water, I follow what the last reviewer said (turn tube to the side where the air filling Velcro cover is, and it drains very quickly) and that works really well. I do wish there was a little more cushion under the bum to protect against the occasional rock, but otherwise, this tube is perfect.
