The RETRO SERIES Lace up Sparring Glove is designed for traditional boxers who want a glove that mimics the feel of competition boxing with a lace-up application. The glove comes in two options, 10oz for sparring/training and competition use, and 16oz for more intense upper body training. The glove features a variety of shock-absorbent foam layers that provide a firm impact that becomes softer over time. The inner foam layers are designed to allow for easy maintenance of a natural clenched fist position with minimal effort on the inner forearm muscles. The built-in finger grip bar provides full control and stability during repetitive punches. The safety thumb tie ensures that the thumb follows the direction of the punch without getting caught unnaturally. The inner glove features a moisture-wicking, anti-microbial lining for comfort and hygiene and perforated mesh palm material for ventilation.
