Great mask
It’s made running with a mask bearable! I had been using a cloth mask and constantly had to pull it up and down. With this one, I can just leave it on and run!

Comfortable Mask (Staff Review)
This mask is lightweight and breathable. The adjustable ear straps really help this mask stand out as I usually have a tough time with masks that do not have this feature. I am able to customize the fit of this mask to my liking by shortening the earloops and adjusting the nose piece. The filters are a nice added benefit and layer of protection. My only gripe with the mask is that getting the filter into place can kind of be finicky, but all in all, this is a great mask for running and everyday use.

Face Mask [Staff Review]
A great mask for long term use. Using the interchangeable filter helps cut down on condensation building up on the inside of the mask and provides a comfortable fit. The adjustable straps and nosepiece are easy to adjust and give a nice snug fit so my sunglasses don't fog up. Overall I highly recommend it!

Face mask
Overall I like for everyday use, my only complaint is when I use them on the mountain as a ski patroller with my helmet and goggles my face gets really warm as they don’t let enough fresh air in.

Let your beard breath! [Staff review]
Great light mask that doesn't squish my beard in weird ways. The adjustable nose piece helps to prevent my sunglasses from fogging up while running and biking. I get the inclusion of the filters for extra safety. They are simple enough to put in, but I don't bother.
