The Sly Pro Merc Arms pads deliver light weight protection that keeps your mobile and protected. The pads protect from the wrist to above the elbow that results in a full arm protection when wearing either a t-shirt or jersey. Using a light weight high density visco-elastic foam gives the players the mobility and compact protection they need at the front lines. Kevlar body for the padding gives the pads a strong lasting appeal that will prevent short life use of the pads. Strategical placing of the pads creates a non constricting protective pad for full range of motion. The main difference between the Back and Front is with the higher density thermoformed padding made for diving.
