I've always liked Davidoff Cool Water. It has always been a real favourite of mine. I have the EDT and the aftershave. The EDT doesn't seem quite as strong as it used to be, though, and it isn't particularly long-lasting, either. It's also quite hard to find the aftershave in most shops now.
I have never known of a Cool Water Aftershave balm before. I'll have to see if any of my local shops have it. Considering how difficult it is to find the aftershave, though, I won't get my hopes up.
