We guarantee you'll smell the difference when you use SWIFF or your money back!
Watch this journalist take the SWIFF Challenge on the golf course:
1) Spray the left armpit of your shirt with SWIFF, but not the right armpit.
2) Go do your thing and work up a sweat.
3) Take a whiff of both pits at the end of the day and smell the difference.*If you really want to have fun, film yourself doing the SWIFF Challenge and tag us on social media #SWIFFChallenge!
