I’m always experimenting with my winter layering system, and one new item that I’ve started carrying on really cold winter days when I go hiking or snowshoeing is a Reversible Polar Buff.
While the Reversible Polar Buff can be configured in several different ways, as Henry demonstrates above, I mainly use mine as a neck gaiter in winter, because I find that it keeps my head and core warm, even when I want to keep my arms and legs cool relatively cool.
When worn as a neck gaiter, the two layers completely seal the top of my jacket and prevent any warmth from escaping, while the fleece helps keep the back of my neck and the blood flowing through it warm. It’s surprising how much extra warmth you can feel by simply insulating your neck in cold weather. I often carry an Insect Shield Buff during the cooler shoulder season months for much the same purpose, since I get so much extra warmth for very little extra weight.
Reversible Polar Buffs differ from regular Buffs because they’re made using two different materials, the regular lightweight synthetic buff material and a thicker layer of warm fleece. Tubes are formed with each material and which are sewn together one inside the other, so you can have the fleece on the inside with the print on the outside or vice versa, in the simplest configurations. You can also fold the buff into a hat, balaclava, or facemask with a little practice as shown in the video.
While I could just carry a Reversible Polar Buff (2.7 ounces) instead of the small hat and balaclava collection I do carry in winter and reconfigure it as needed, this is a garment I mostly throw into my pack as a “secret warmth weapon” for really cold days, when it helps to augment my heaviest hat with a neck gaiter for greater warmth.
