Review on 🧢 Chaos CTR Adrenaline Skull Cap and Helmet Liner - Ultimate Performance for Your Head by Jonathan Fernandez

This beanie is thick, light, breathable, fairly warm and thin enough to fit under a helmet (although I had to loosen the helmet a notch, but I keep my helmet pretty tight). I prick my ears to protect them from the wind, although they may be too small for a person with a large head. It's more or less a windbreaker, but together with a helmet it also keeps you warm. The best part is that you hardly sweat in it, although it keeps you very warm. On very cold days (particularly when there is strong wind) it is also very suitable as a second layer under a hat. The only reason I'm giving it 4 stars instead of 5 is that the elastic around the edge can squeeze your ears a bit and cause discomfort after an hour or so. A bit of padding would be nice here, although it might prevent it from going under the helmet. However, it's not something I'm going to wear all day, which isn't ideal for any garment. But I mainly use it for cycling in the cold and wind, for which it is definitely comfortable enough. In short, this is a great cap! There can be a little more comfort around the ears, but that's only an issue if you're wearing it for several hours.
