Knox Defender Elite MKI Shirt

The Knox Defender Elite Jacket is the result of valuable feedback from riders who wanted all the benefits of a standard Knox armored shirt but with extra protection on the shoulders, elbows, chest and lower back. The Defender Elite is a highly breathable armored shirt perfectly suited for either on or offroad riding. It comes with CE approved Level 2 armor on the shoulders and elbows and has the added benefit of a full length Aegis Level 2 back protector and chest protection.
