Review on 🧢 EMPIRELION Lightweight Thermal Skull Cap with Ears Warmth | Cycling Helmet Liner for Winter Running, Beanie Hats with Sweat-Wicking Technology by Brad Lovro

This cap is only meant to be worn at night while I sleep. I don't need a thick, very warm hat for my purpose, but in winter my head needs to be warmer because the air in my room is cool at night and I wake up with a sore throat and blocked sinuses. Knowing how much warmer I feel when my head is covered, it made sense to wear something to keep the heat from escaping. I've found wearing a knit hat helps. It's very thin, so it's right for my situation. It's not too thin to help.
