Surfing Waves

Been reading all the posts about how best to store keys and was interested in the Bubbleloc Rash Vest. Just wondered if anyone had this and if so how they found it.

I have an electric car key so need it to be totally water tight (may well look into getting a manual key cut anyway though). Also liked the idea of not having a separate loose wallet to lose. I figure if its in my top I am unlikely to lose it!!!

Really just wanted some comments on whether this seems a good buy or not. Also is it uncomfortable to wear or awkward being over a wetsuit?

Thanks for any advice
