I've always suffered from bad B.O., coupled with excessive sweating. I've used Mitchum and Shield (Rexona) Sports 48H protection. I found Mitchum would, over time, destroy my clothes with like a hardening of the fabric from the armpits. The Rexona roll-on leaves a white residue but the spray was working well. Eventually, I ended up with an extremely bad odor and I put it down to the spray. I researched online and the suggestions are to use a natural deodorant. I looked at Dr.Squatch but it looked overpriced - except - they have scents that are far more interesting to me as a Man. I settled on No Pong, I'm on my second tin. It works very well. My smell is pretty much gone - although - I still have my sweat problem. I sometimes still swap a shirt during the day but it is not from the smell - it would just be from me sweating. This has been far better than the other deodorant brands. I was skeptical given that you have to use your fingers to rub it on, but it hasn't been too bad, I just do it after a rinse or shower. I only wish that they'd get some more manly scents.
