CCM's Extreme Flex E3.5 senior leg pads offer many of the same features of the high-end version while reducing the price for the cost conscious amateur goaltender. Like its predecessor, the E3.5 has a tremendous amount of flex throughout the thigh and knee; what's changed this time around, however, is the re-engineered foam core that is thinner at in the thigh rise, both reducing the weight of the pad and lowering the centre of mass below the knee. The new, lightweight design also offers QK5 strapping, to maximize rotation in the leg channel for a quicker, cleaner butterfly. The top strap is adjustable and can be attached at the knee or below it. CCM has also retained the ultra-wide knee cradle to accommodate modern knee pads in addition to a solid knee block for butterfly stability and excellent coverage. Lastly, the CCM E3.5 leg pads feature CCM's new Speed Skin technology, which reduces friction when sliding, resulting in more efficient and explosive sliding.
