excellent gloves, def have to size up. I usually wear a large and got the XL, fits perfectly. I wore these during a century, it was like 60ish degrees in the morning and my hands stayed comfortably warm. I wore them during a 45-50 degree day and your hands get cold at first but ended up warming up. I'm not sure about 30 below days though. Decent price and quality for $30 gloves.
