Accessories are also important, and your appendages must stay warm. Having cold hands can detract from a good run, even if the rest of your body is warm. I wear running gloves but sometimes I wear a pair of wool mittens over them. (You can slip hand warmers in them too.) Next, I like to wear a dickie collar, in the form of a fleece. My go-to is the Dik-Dik by Matek, which is a brand that is actually geared toward skiers. Finally, for headgear, I like to wear a snood-like cap that protects my face too. If it’s dark out, I recommend wearing a hat that is highlighter-hued.
