Outdoor Research Lumen Balaclava - Lightweight Ski Mask for Cold Weather, Hiking & Snow Sports - Windproof Face Cover for Men & Women - Perfect for Skiing, Snowboarding & Winter Outdoor Activities

The fabric is so thin that I didn't think it would keep me warm but I am glad to tell you that I was absolutely wrong. In a strong wind it easily kept my face and neck warm.This product is as good as they come. It covers my neck well and it's versatile so that I didn't have to use it just as a balaclava. The fact that it's so thin makes it great to keep in a coat pocket with room to spare, it's not bulky at all (it's like a folded bandana).
