Haven't seen those yet. Though I should probably get some of those SOSpenders, as I don't wear anything now. I have a Nav II, so I don't worry about sinking. If I manage to pop all three bladders (the small backrest is storage now) at once I figure my time must be up. That would have to take an act of God, or an acident so bad that the emergency bladder would be worthless. But for those of you who use the U-tubes and Round tubes I would get one. I have a U-tube, I used it once and am going to sell it. I'm just too damn big for it. After my Nav, I felt like I was going to roll over at any time in it. It's my spare until I buy a replacement. Though I think it might be bought by a freinds friend before then. The one time I used it I kept thinking of what a blow out would mean, w/ only that tiny little backrest to hold up all my gear. I can swim, but the rods and plastic can't.

Where did you see these new devices? Are they Caddis' response to their leaking valves?
