RKD snorkel mask anti-fog testing comparison with other mask

RKD R10 full face snorkel mask is designed for adults,the size have have S/M and L/XL, it's a 180 degree wide view design so you can have a 180 panorama view when wear the mask.

The mask is anti-fog design,this is very important, usually when wear the mask and snorkel,if you breath there will be Co2 come out and will have fog in the mask, but our mask have a better inhale & exhale system, which make sure the Co2 push out of the mask maximizely when breath,so you even can't find fog in our mask when breath, but other mask do have fog come in the mask.

The video a testing to show our mask anti-fog design is much better than other mask.
