The ProSeries is our original and most popular model, It’s a protective glove with good comfort. The glove is not bulky, weight has a balanced feel, it has a comfortable secure fit. The ProSeries knuckle area is composed of a combination of three different polyurethane foams. Together the combination makes for a mid-dense feel. It’s a good glove for multi-use. Smaller sizes 8oz- 12oz have a fight glove type fit.
