The Alpha shin/whip pad uses a perforated neoprene with air plush lining together with super stretchable neoprene straps. To protect your shins from pedal bites and other impacts we use a Nylon hard shield with EVA foam backing and a super durable Cordura front material. We also added extra padding on the inside to protect the inner part of your leg when catching tailwhips. Extended for upper shin area protection.
