A narrowed set of TF3 knee impact armor that's more comfortable than the standard riding--suit sized TF knee armor inside the knee armor pockets of Aerostich Protekt Khaki's and Jeans. Same height as standard TF knee armor (10") but 1.5" narrower (6" vs 7.5"), so it fits and feels better in these pants. Also will fit the knee armor pockets in Classic Roadcrafters, R-3's, Darien and AD-1 pants. A fitted black Supernyl bag encloses each knee armor pad.
