A rib vest helps absorb and evenly distribute impacts and vibration directed through the chassis into your body helping reduce the chance of injury and allowing you to focus on the task of driving rather than discomfort or exhaustion. Musky Puff rib protectors are ergonomically constructed to provide protection for the ribs and kidneys. The durable Cordura construction incorporates dual-density, ergonomically shaped protectors. Constructed from a robust PE hardshell, with a fiberglass core for impact and shock dispersion. Fully adjustable with double ring fastener and Velcro straps. Offers complete range of fit allowing protection to be worn under or over garment.
