I have Warrior, CCM, and Brian's knee guards.... I purchased these and they are so much better than the others! I have finally found the blend of comfort and protection I have been searching for. They are NOT as bulky as you think since they are pretty well rounded, they allow your pads to rotate easily. Also, they do NOT slip down since you slide your leg in and then strap them. I feel like it's a constant battle with my Warriors to keep them from slipping down, not with these though. Great knee guard, highly recommend
