I was looking at getting a pair of bag gloves from mmawarehouse.com and they have the size M in stock. It says that they are to be used by people ranging from 100 to 150lbs and L for 150 and up. My question is would I be alright with the M, I am 5'8" 175lbs but wil be cutting soon and should be around 160-165lbs. I have somewhat small hands and was just wondering what you guys thought would be best. Thanks alot. BTW, they will be used with a heavy bag.
