These gloves are for training and heavy bag work. Crafted from durable neoprene, flexible mesh, and an elastic wristband. Approximately 7oz. The knuckle foam and palm grip create a protective cover for your hands. Designed to support speed and power during training. One Size Fits All. The elastic and flexible material allows these to fit any hand size. The gloves are machine washable (but not recommended more than once a week). They are thumbless which makes them easier to pull on/off, use your phone, and change the song. The inner lining is manufactured to be moisture-repellent which offers a comfortable, dry, and smell-less experience.
