Ye I only use antiperspirants under the arms when it is really hot and I need to wear a suit. Otherwise I use hugo boss, 3 squirts. One on the centre chest, one on each of my collar bones/neck. I don't use deo under the arms.
Funny thing is that since I stopped using Deo and turfed all the old shirts that would smell very quickly once I put them on. I actually dont have BO at all on a normal day.
