I guess I can speak for the younger generation as I like to consider part of that generation still (25 years young). yes Old Spice is very popular most of the time not in aftershave form but in deodorant and body spray form. Thanks to the Old Spice guy.
Most millennials have no idea what aftershave is and don't use it. Only hipsters really....
I've used the original AS but I don't currently have a bottle.
They've done a great job of keeping classics and marketing to a new generation.
I always have various Old Spice brand body wash and deodorants on hand.
