The Exoskin Shin & Whip Guards from Triple Eight cover you from below the knees. They have a high density front and since they are thin you can wear them under your trousers. They offer protection for various sports like BMX and mountain biking.
They are made of perforated neoprene with inner lining for breathability. The high density area is made of molded PE and shock absorbing EVA foam makes additional protection beneath the PE.
These protections have four velcro straps to create a secure and good fit.
