The Optik X3 blocker also uses an internal lace sidewall which makes this blocker more streamlined compared to the previous generations. A seamless binding face allows for maximum surface coverage. The palm of the Brian’s Optik X3 blocker uses a No Slip SBA Synthetic Palm Material. In the wrist strap area, the X3 uses a flared cuff for added wrist mobility. An adjustable velcro strap across the back of the wrist allows the goalie to customize how tight or loose they prefer the fit of the blocker.
