Can still provide good protection performance in extreme temperatures.The pad is soft when it is not impacted, and becomes hard when it is impacted for protection. NON-SLIP: Hook and loop adjuster for easy donning. Knee pads use stronger buckles. Different from ordinary knee pads, we adjusted the hook and loop position to just the right, non-slip while making the wearer not feel its presence.The inside of the knee pad has a gle anti-slip coating to keep the knee pad in place during exercise. HEAVY PROTECTION：The knee pads use multiple layers of protective pads, which are divided into protective layers and comfort layers. The total thickness of the pads reaches 3/4". Enough to handle all kinds of emergencies. WEAR-RESISTANT: The outermost layer of the knee pads is made of wear-resistant fiber material.
