There were snaps at the neck opening.  rashguards are made to cling, which can sometimes make them difficult to take on and off.  This has a good opening at the neck, but if you've got a baby with a 60+ percentile head, I'd be wary of buying a rashguard that didn't allow you to expand the neck opening.

Other than that, I like it.  It's white, so it can be passed down to an opposite-sex sibling.  Fits my 17lb-er well, with room to grow.
