Currently I have an old Neil Pryde buoyancy vest and the camelback is in a cover with tabs so I tie it on. I think it's at the end of it's life and am looking at options to replace it.
I've seen the backpack type ones but I don't want to wear 2 vests..Do any new buoyancy vests have a pocket to store a camelback in or have you seen any camelbacks in a cover that have attachment points?
Here is the current solution.

Check out the Unbottle. No storage at all but will clip to your vest or tie with some outhaul. 3 or 2 litre by the looks. And a weight for when it get heavy wind

Thanks that looks the goods..
Yep I use it as weight although I drink a lot so it gradually gets lighter as the session goes on..

Ordering the 3ltre now..
