It is certainly warm enough although the mesh opening around the mouth allows a fair amount of wind chill to the lips. The down vent over the nose is not formed so it allows the escaping breath to rise and fog glasses/goggles. The velcro closure is bunched and is somewhat difficult to align and seal. It is fairly tight, if you have a large head like me, and that also makes it a little difficult to adjust. It took weeks for me to gt this item as it did not ship on the date promised from the manufacturer. If you are looking for high functionality and to get a balaclava in a hurry you should look at one of the more expensive options.
