My favorite PFD...
is a 'SOSpenders' auto-inflate with an integral harness. It is comfortable to wear for long periods of time, it is relatively light weight and unobtrusive, not too hot in the summer and seems like the best bet for most applications. Sure, it's a little expensive, (about $200) but I figure if I ever do go in the drink unexpectedly, it's worth every penny. Inside the jacket is a whistle, line knife and a floating strobe light, I'm currently thinking about adding one of those new 'rescue streamers' as well, as they look to be a really good idea. The auto-inflate feature also lends a certain peace of mind if I should happen to catch a jibing boom in the noggin before I get tossed in the water and am too 'out-of-it' to think to pull the activator cord. Oh, and hey, Chris Burti, as to your question about the kid-sized PFDs, I just got a foam with auto-inflate jacket for my 7 yo nephew a few months ago and he loves it! BassPro had them on sale and he's always been a bit of a whiner when it comes to wearing a regular 'horseshoe' type vest (can't really blame him when it's 100 degrees!) so everybody is happy now, especially his Mom! (she's convinced that sailing is inherently dangerous and makes him put on a vest before even stepping onto the dock, even though the kid can swim like a fish!) (little sisters never really stop being a pain in the butt, even when they're 35 and have a kid!)
