To the guys who run where it gets cold - what do you wear to run? Between 0C (32F) and about -10C (14F)
Layers! I start with a solid set of compression boxers (support and sweat wicking), then add a layer of tights (something with added padding in front for warmth) - both of those layers are currently Under Armour from
Amazon. I pull a pair of Saucony socks overs top of the tights to keep the breeze out. Then, if it's really cold, I'll add a pair of shorts before I put on my track pants. This keeps my legs warm even down to about 15F.
For the top, it depends how cold it is. I usually have a short sleeve sweat wicking shirt (UA), then a long sleeve tee over top (either tech or cotton, depending on the temp), and then I put on a padded jacket. I like the Amazon Essentials Stretch Quilted - I have two of them in different colors. I like that it's zippered, so I can regulate temperate by unzipping. It also has two zippered pockets for storage (like when my gloves get too warm and I strip those off). It also has the thumbs holes for really cold days to pull over your wrists, but then I find it hard to see my Garmin. With all of this on, I'm usually pretty warm.
I usually just wear a thin pair of running gloves. Starting out my hands might be in my pockets off and on, but they heat up pretty fast. If it's super cold, they'll stay on the whole run, but if the sun is out and it's not windy, then they'll come off after about 30 minutes.
My ears are always an issue for me, so I also wear a thin headband. It's sort of like a pair of thin earmuffs, but it wraps around the whole head. I like it because it keeps the sweat out of my eyes and I can also regulate temperature - too hot, roll them up, too cold, roll them back down. And if it's really too warm, take them off.
Maybe a ski mask like this would work.
I tried one of these in December, but it didn't work really well for me. It kept slipping down as I ran and was uncomfortable. Instead I use a thin neck gaiter made out of something stretchy (it was a COVID purchase even though it turned out to be completely useless against the virus). I can usually pull this up over my ears, sometimes even the back of my head, but it still covers my neck. I also like this because I can tuck it down my jacket and there's no breeze blowing down there.
My last trick, not clothing related, is to use warm water when I'm mixing my sports drink. It doesn't stay warm for too long, but it's usually long enough that it's not frozen after 30 minutes. I really hate being cold all over and taking a sip of ice water. Brrrr!
