Take The SWIFF Challenge

We guarantee you'll smell the difference when you use SWIFF or your money back!

1) Spray the left armpit of your shirt with SWIFF, but leave your right armpit unsprayed.

2) Go do your thing and work up a sweat.

3) Take a whiff of your shirt at the end of the day and smell the difference. Better yet, give your shirt to a friend or family member and have them smell for you.

*If you really want to have fun, film yourself doing the SWIFF Challenge and tag us on social media #SWIFFChallenge!
