Bought these based on other reviews and will definitely make these part of my umpiring gear. Based on using this great product, playing in a tournament, switching was hard to even think about going back to what I was using or using any other product. I will admit that the feel at first was different, even a bit awkward, but that goes away quick I would highly recommend this product.
