Being hair challenged, I need more head covering then most. During cold weather I use/wear two or three at the same time. I have and use the following: KOM bomber (the warmest), Gray Wolf Bomber (I use this one the most), wool watch caps, fleece balaclava’s (made by my wife), wool/synthetic ski Balaclava’s (full head but open faced), neck gaiters, and scarf’s (Silk). I mix and match combinations of these as the weather dictates. One note, both the KOM and GW bomber are large enough to fit over the other head coverings and are insulated wind stops. The biggest drawback with this setup’s is the loss/decrease of hearing but I’d rather be warm and deaf then cold and able to hear.
