These work very well to keep your toes warm in cold, dry weather when you don't need to wear rain booties. Easy to put on. The only downside is the wear on the bottom, but I think this is the case with any toe covers.
Bought this to wear on early morning commutes below 40 degrees. So far very happy with the product. Keeps my forehead and neck warm and absorbs sweat well. Would definitely recommend for colder temperature riding.
This is a great product when the temps dip below freezing. I've worn it in temps down to the low teens and nasty winds and the warmer does a really good job at keeping me protected. The fabric itself is fairly thin and doesn't seem like it would do a good job, but it really does. I typically just put it over my mouth and nose on descents and pull it down when I am climbing. The few times that I have left it on my face climbing it does seem to allow a decent amount of airflow out so my glasses didn't fog up. I've been using it for about three months now and love it. All around great product, no complaints.
I use this with a skull cap and it is long enough that I can pull it up in the rear and capture it under my helmet to securely hold it in place. It can easily be pulled up over my mouth & nose for extra warmth. Good stuff.
