K1 RaceGearK1 Race Gear Coolmax Vented Head Sock/Balaclava (White) - 17-CHV-W

Very good product…

This head sock is great! It fits my fiance great and keeps him cooler when hes racing.

Many descriptions here will complain about the size of this head sock. They are accurate. I wear an XS sized helmet, 57cm and this barely fit me. It is not shoulder length but ample enough to cover the head and most of the neck area. For me, this works well because the 3 contact points: chin strap area, cheeks and top of head are covered by the sock and will keep the helmet clean. Coolmax will keep the wick from the head and will dry faster than other fabrics. My only other complain is regarding the sewing seams. When wearing it, after a while, the seam on the top of my head began to dig into my scalp. By reversing the sock inside out has remedied this problem without changing how the head sock works. There are probably better head socks out there.

I actually bought this for use under my welding face mask and it’s comfortable and breaths well

this thing is TINY and won't fit an adult head, especially a big one like mine. doesn't seem very stretchy either.

Bought this for my son to wear underneath his helmet while riding his go-kart. Works well for what it is but the seams seem kind of thick and stick out a little. Does help to keep the sweat out of his eyes and make the helmet slide on an off a little easier.

This didn't come with any sizing options, and is extremely small, no way an average size adult could wear this.

Perfect for kid racer
