Compression Pants / running tights are an absolute must in cold weather. I’ve found that the expensive, name-brand ones and the off-brand ones are basically identical. Save your money and buy the generic ones from Amazon. There are a ton of brands, but I happen to like Runhit. These run pretty long, so they’re great for taller runners; if you’re shorter than 5’10”, consider the 3/4 compression pants.
