Review on 🧣 Black Halo Headband Skull Cap with Anti-Freeze Technology by Trevor Rodke

I bought this to bike to work when the temperature started to drop. I used to wear a wool hat under my helmet but the helmet didn't fit well and I was always sweating. It's the perfect combination of breathability and warmth (20-30F range for me). After an hour's drive to work, I wasn't sweaty, hot or cold, just comfortable. If I find it won't withstand further temperature drops I'll update this review, but for now I suspect it will be fine down to 10F.
