I've used these for about 5 boxing classes now and I've had no problem with them. I kept getting bruises from the heavy bag with the thinner ones that were included in a package set with the heavy bag that I purchased. These were much thicker and a much higher quality. We even do push ups with these on (yes push ups with your knuckles), and there is really no sign of wear. I paired them with the linen scented glove deodorizers and they even still smell great. I would recommend these to anybody because of the price and the quality. Great for someone who boxes a few times per week.
