I have been out of the water for the past couple of years and am ready to get back at it. I will be taking my 14 yr old grandson and want him to wear a life preserver. I know the big bulky ones are out of the question and I've been reading a little about the inflatable type. Does anyone on here have any experience or could you recommend a certain type. Price will come into play and the recharging price is important to. Any help would be appreciated.
