Re: Life vests for the well-endowed
Most if not all inflatables have a blow up option via your mouth. This way if the cannister does not inflate it all the way, you can, or if in the water a big, it starts to deflate say due to colder water, you can increase it.
Having all of the same pfds is good as you say, so you only need one or two rearm kits on the boat at any given time. Especially since they run about $30-50 per kit! depending upon the type etc.
