That is definitely a lot of stuff you have. I don't have near as much as you do. I bought a bottle since it's cheap enough and find it to be nice. Not necessarily anything that blows me away but it's a nice fresh scent. Funny enough I was digging around in a drawer that I rarely going into and that is filled with stuff I've put in there over the years and I found a tiny glass bottle of a Gillette Series aftershave called Pacific Light. Interestingly the scent coming from the bottle smells very close to the CoolWave. I'll use that one when I travel.
Let's see. Not many I think, Proraso Green. My Favorite for cooling in warm weather. Aqua Velva Ice Blue, (it's ok, would rather use Proraso Green). Won't buy again. Original Sport (Canada), not a fan......smells cheap because it is. Won't buy again. and Musk. Not a fan. Won't buy again. Mennen Skin Bracer. Not bad, might buy again. Old Spice. Fantastic year round except warm weather when I switch to P-Green. Brut. Meh. Tabac. Fantastic, my favorite cool weather alternative to Old Spice. I think I could minimize the aftershaves down to those three (or four with SB). Proraso Green for the 3 months of the year that it's actually warm in British Columbia. (June, July, and August) Maybe Skin Bracer thrown in for a change. Old Spice and Tabac for variety from September to the end of May.
