Physical Success Partners have designed some pretty good looking boxing gloves for kids, ages 2-7 years young. Currently are selling on www.amazon.com & www.ebay.com.

I believe that our kid’s boxing gloves have the quality of real professional boxing gloves and kids deserve to have a good quality boxing gloves while going to Martial Arts classes.

Designed with a Velcro closure for more protection. Our boxing gloves have been completely redesigned to conform to the shape of your kids for maximum comfort, grip, and support. Softer, more pliable top-grade vinyl is now being used in our boxing gloves for extra comfort and durability. We now use a Sorbo-shock grip and a combination of chosen foams, a smooth water-resistant satin lining has been added to provide greater comfort for your kids hands.

Better than the Everlast kids gloves!, August 3, 2015
 These gloves are constructed the way adult gloves are constructed. If you want a well made product that doesn’t feel like plush make-believe gloves ala Everlasts kids gloves, these are it. These are fantastic. I purchased these for my 4 year old and he’s motivated to train, play, and learn the sweet science because he can see that he has the exact type of glove the pro’s use only in a smaller package made for him! Highly recommended.
Awesome gloves!, November 17, 2014

These boxing gloves are wonderful I highly recommend them, my son practices almost everyday! If you want to train or just have fun with them then these are a great purchase.
 I ordered these gloves for my son for Christmas. It may be a year or two before he really can get some good use out of it since he’s just 2 1/2 now, but my nieces tried it out and it seems to be pretty durable. Good value for the money, especially since it’s hard finding gloves this small.
