Stand21 Porsche Motorsport Nomex Balaclava 1 "a"
I am very happy with the Stand21 balaclava. My previous balaclava had a seam from front to back starting in the center of the eye port. The extra seam thickness pushed on the center of my forehead and gave me a raging headache in endurance races. Purchased the Stand21 since it moves the seam over to the sides of the eye port so there are no seams on your forehead.
The balaclava I received did not exactly match the one in the photo. It does not have the seam from the bottom of the eye port and has a small hole for your drinking hose at the mouth, but I consider these to be fine. The material also stretches enough to pull the eye port low enough to expose your mouth for drinking.
If you wear it to protect yourself while racing, the DiscoveryParts.com Driver Gear collection is where you'll find it!
