The Kali Protectives Aazis Plus 130 Soft KneeShin Guard is 50mm shorter than the 180, but it still uses perforated neoprene, a soft shell knee cup and shin plate, and Nitrex high density foam to protect without restricting pedaling. The plates are constructed from flexible ABS plastic, so they're impact tough, yet able to give for excellent mobility. In abrasive zones, an Aramid weave expands protection and ensures durability. The Aazis Plus 130 Soft KneeShin Guard features an anti pull down design that works to prevent migration when pedaling to keep the guard in place. It is fully washable, and antimicrobial materials help keep odors at bay. The Kali Protectives Aazis Plus 130 Soft KneeShin Guard comes in sizes Small through X Large and in the color Black.
