I read a review in which one reviewer said after he installed the grip, the grip moved around. I thought if I stretched the grip tight during the installation that I wouldnt have this problem. However, the overgrip was installed on a Head Graphene Pro and the most used part, bottom half, began to bunch together and there is a gap now where the original grip shows because there is no overgrip covering it. I guess I would be in the consensus that this grip can slide and bunch. The bunching up is probably due to the tiny perforations that make the overgrip fold onto itself.
