Heatwave Performance Lazer Face Slim: Vapor Clear/ Anti FogThe SLIM is the proverbial Goldilocks of Lazer Face universe. They feature the width of the standard version, but with 5mm less lens height and a repositioned nose piece, bringing the SLIM to sit further down on the face. The changes are subtle, but the look and fit is drastically improved if you ever thought the original Lazer was just too loud.
