We live in Northern Maine where the temperatures reach -50 degrees F with the windchill. This mask is exceptionally warm and does wonders for keeping out the icy chill. The material is comfortable, not itchy like so many other products. Breathing is easily done using the vent system. It can cause a little fogging if wearing glasses, but it's not enough of a negative to detract from this review. My husband used this to walk to and from work, which is approximately 1 mile from our house. He felt it was not something to go jogging in, but it handles walking just fine.

Got this for running in the winters of Western New York State. Harshest conditions tested were ~6 miles in 15°F, no precipitation, strong winds. I am 5' 9", 145 lbs. Mask size of Medium fits perfectly.

Warm, but not to the point of being stuffed - right in comfort zone. There is some space between mouth and actual mask, so it does not stifle or hinder heavy breathing even during heavy work (Z4, Z5 heart rate training). Additionally, the nose is unobstructed, which is also a boon to heavy workouts. The water vapor from my breath did end up making this portion of the mask wet which clearly became cold, but this did not regularly come in contact with my skin.

The fit covers the lower part of my ears, which makes it slightly difficult to position comfortably AND securely, though this is far from a mitigating factor. Put my hat between the mask and my ears and had no complaints. Mask held securely for the entirely of the run.

Most definitely recommend to anyone who wants to run in deep winter, but doesn't like treadmills.

Every so often it is so cold outside that I risk an injury to the exposed skin on my face - mostly my cheeks or my nose.
The Seirus Neofleece is the perfect blend of modern fabrics. I get a nice soft scarf around the back of my neck and neoprene in the front that won't absorb any moisture and stay flexible in sub zero temps. This product is well made and durable.

This face mask vents well and is adjustable - I can get a perfect fit even if it take a couple of tries.
My cheeks and my nose are protected and I can train longer outside when it really cold. I recommend this to anyone who needs to protect their skin in cold weather. It really works well! A great product.

Keeps my face warm! Does what it's suppose to do. I got the large and fits me just right withouth feeling too tight on my face. The inside face guard is like fleece, so provides for that extra protection in freezing temps. I live in Chicago so our winters get pretty cold, especially when you factor in windchill it can feel like below zero temps! The neck guard prodvides decent cover around my neck, but I still use a scarf for extra protection cause the neck guard isn't that long. Overall this is my favorite winter accessory!

I walk my dogs 365 days a year here in Northeast Ohio and I have no idea why I didn't buy one of these sooner! The worst part about walking in the winter is the wind on my face, and scarves are just a pain in the butt. This keeps my face warm AND my ears and doesn't move or fall off or flop around in the wind. It doesn't fog my glasses, either! It's easy to breathe. Plus it's not too hot - I've been wearing it in 40 degree (F) weather that's not too biting and I'm not sweating or wishing I'd left it at home. Walks are SO much more enjoyable now!

I've got a super large head and a ton of hair but the Large size fits just fine.
