Though there are several smaller variations of the X-Shield, the full face mask offers the most protection. Naturally, this product is also designed to protect your face while running at high speed in your bass boat, but make no mistake...the X-Shield is intended to be worn all day in lieu of shades. Tredup also paid close attention to the specs. The full mask weighs just about five ounces, and he labored over materials to make sure the mask absolutely will not fog. You can get yourself an X-Shield for $60.
