The perfect evolution of the flexible, dynamic and agile performance that you have come to expect. Featuring the new DRS PRO integrated knee, you'll get maximum seal and stability, all while moving even faster from one save to the next. Not to mention, the hyper-absorbent knee stack design and the QMSS 2 are built with butterfly biomechanics at the forefront. Constructed with a flexible design below the knee and into the boot for smooth movements and added stiffness for greater butterfly seal and stability above the knee, these pads bend to your will and react to your every move.
