OXYFIT™ Sport Nasal Strips

I used this product during hiking several times. When the temperature was around 35-40 degrees it stayed on and was great! However when used it on a 50 degree day as soon as I started to sweat, it lifted off. I cleaned my skin well both times per instructions. Unfortunately they have a strict refund window and the temperature change accured after the time allowed. I can’t recommend.

It works but the problem is it doesn’t stay when you sweat. I ran today with it, it was hot and it lasted only 3 miles.
