Review: Comfort is prioritized. - (Disclaimer, I removed the RaceQuip logo in the front with a seam ripper. But rest assured, this is the very same item.) First of all, this is a great head sock. I intend to use it for a cosplay which involves wearing a helmet and a gas mask on top of that, which I tested. Easy compatibility with both. It’s thin enough to support other head accessories like racing helmets, which obviously it’s intended for. It’s also VERY easy on your face. Firstly, the material is VERY soft and comfortable. No annoying seam going over the mouth, either. It’s a perfect fit, tight enough to hug your face just ever so slightly, but loose enough to get comfortable mouth movement. The eyehole is also excellently cut. Large enough so that practically nothing obstructs your view, but still enough material to guarantee that it goes over your nose without fear of it falling down. You can also pull the nose part down below your chin if you wanted. It also seems as though the neck covering is the perfect length. Just enough to cover the entire neck and get tucked under a shirt. And finally, the breathability is fantastic. Light and easy. Everything about this head sock feels as though it was meticulously and considerately designed for user comfort and applicability, and everything about it hits the Goldilocks zone for me. Just right. It does exactly everything it’s supposed to do. If I ever lose this one or it somehow gets damaged, I know where I’m coming for round two.
Review: Head sock for racing - Works great for under racing helmet. Light weight material really helps.
