comfortable

The installed non skid tape everywhere at work because noncordinated people where falling and hurting themselves. I am trying the double knee for first time. I had the normal and they lasted well till installation of tape then they lasted only 1 month till knees where completly worn through. I have to do a lot of crawling on hands and knees. I purchased the loose fit because they where on sale. The next time I purchase I will go back to regular fit it is way too much room for me. I have had them for a month now and just getting the normal snags no rips or holes all the way through. The material in knee area is standing up well to the 80 grit skid tape.
