Good but dries out if left open

The product works great when fresh, but I accidentally left the cap off overnight and the tip dried out. Make sure to close it tightly immediately after use. Once I got a new one and was careful, it worked perfectly.

Works well but needs reapplication

The anti-fog effect is strong, but if you are doing a very long training set over two hours, you might need to reapply once. For standard recreational swimming, it lasts the whole time. Great value for money.

Better than sprays

I used to buy spray bottles that would leak in my gym bag. This pen format is perfect. It stays contained, applies precisely to the lens without dripping, and fits easily in my swim kit pocket.

Essential gear

Simple, effective, and affordable. It doesn't leave any weird residue or smell like some chemical treatments do. Just clean, clear water visibility. Will definitely buy again.

Game changer for my morning laps

I swim every morning and foggy goggles were ruining my routine. This pen is incredibly easy to use; just a quick swipe and rinse, and I'm good for my entire hour-long session. No more stopping to clear my vision.

Professional quality

As a swim instructor, I need clear vision all day. This Decathlon pen performs just as well as the expensive professional brands I've tried in the past. Highly recommended for coaches and serious swimmers.
