I use the Baby Warma at the pool because it's a little cold (84 deg) for my 9 month old. It does make it easier to keep a hold of him and it seems to ward off the cold for a little bit, but he still starts shivering after 20 minutes or so. It's very easy to put on and take off. I wish the velcro was a little more adjustable so I could get a tighter fit on my skinny baby.

My son who is four months old has swimming classes and he fits perfectly in the swimsuit with room to grow into it.  It is so easy to put on and take off, I just love this swimsuit very much.  It also keeps my son warm, because he doesn't cry.

Not the easiest to get on, but once you do, seems to keep the little dude warm. He's about 19 lbs., and I forget how tall, but he's 10 months and these fit really well. FYI - the velcro is super-grabby, so if it attaches to the neoprene it'll make the suit's fabric start to wear right away.

Easy to wear
Keep warm
