Your motocross baselayer is your first line of defense. Defense from what, you ask? Defense for sweat and heat thanks to the evaporative cooling properties. Protection from fatigue courtesy of light compression. And, coverage from impacts and abrasions thanks to plated armor. Yep, these aren't your typical gym-selfie baselayers. These baselayers have a little more to them - all wrapped up in a sleek, low-profile package that fits comfortably under your jersey or pants.
