I was wondering how well these gloves hold up, in sparring matches(karate). The gloves I have currently are the "ProForce Gladiator Cobra" gloves, and the outer layer, whatever material that is, began to shed like crazy. I don't know if this is normal or not. But it is annoying and gets everywhere. I don't want to purchase another pair of gloves of that quality.

I measured the size of my knuckles(fingers spread a little apart) and came up with about 9 inches. What size should I get, for this product? Medium, or Large?

I was wondering, I need a glove that is durable enough to last a couple of years of heavy sparring and that had enough padding to safely protect myself and my partner. Would you go with this particular glove, or something like the "Open Thumb Loop Combat Gloves by 'Fairtex'"? Any recommendation will be highly appreciated. ($60 or less range)

Thank you for your help!
