Finally got down into the low 30's so I could try this out. Very happy with the fit and the comfort. This is not stretchy so "snot rockets" require removal of the balaclava. I was very pleased with how well it stayed in place. I don't push myself on these cold weather rides. I am just trying to spend time up on two wheels. I was able to breath without issue, but if I was really pushing myself, I would not be getting as much air as I would want. You are drawing your breath through little holes instead of a big opening. This way is much warmer and I wanted warmer so no complaints.
I bought one for my wife who is an avid gearhead like I am and who rides fat bikes in the winter. There was only one size when I bought it, and so I thought it would have enough forgiveness to fit any had with hair. Not so. She found it very uncomfortable and way too tight for her taste. I tried it, and it's okay for the first 20-30 minutes, but then it does get annoying. There is not nearly enough forgiveness in this fabric. A good product, but probably best for a 2 mile walk with the dog.
Earlier this year used in the Silver State 508 where the overnight temps dropped into the upper 20's. Having this Balaclava kept me in the race and kept me nice and toasty. I strongly recommend this product as the ultimate accessory for cold weather riding.
I was considering whether (weather) to buy this product. Its description does not fit even mild winter weather. What else do you have? I use to wonder why I could not find warm gloves for winter commuting. When I move back to Minnesota after retiring how will you all keep me warm when it's 20 below?
