Curve.......but i've had the bottle for like 5 years. i RARELY use it.
i find that most folks who regularly use cologne.....use about 4 times too much.
yer supposed to waft a hint to others......not warn them from 100 feet away.
I have a bottle of Polo that has probably way exceeded its shelf life. I struggle with the sprayer dealie - if I go for a full spray it is like 5 times the quantity I would ever wear in public.
If I get sweaty or have some other reason to mask an odor I just take a shower. If I was going to wear a manly scent it would be something from Hermès, because that always reminds me of the time some travel issues got use a cheap weekend at a suite in the Clock Tower in Dijon.
