Hi GZB - Chrome is very nice, fresh and clean, safe, CK one - ish.
I think Guerlain Vetiver is really spectacular in the summer time. I broke a huge bottle in my lugggage recently while traveling and the luggage smells heavenly today. It's very affordable at www.scentiments.com
Mugler Cologne is a clean, soapy, summertime frag as well.
I wore Deisel Fuel For Life while vacationing in Cancuun last summer and it was lovely.
I also think Kouros is a wonderful summer time frag. I grew up on Miami Beach and wore it all the time, it's a rockin' summertime frag.
As for new frags, I just received Luck and Love from Ed Hardy from a friend. I really like it and think it will get a lot of action for the summertime. It's on the lines of Silver Mountain Water and YSL Homme.
Have a brilliant day!
