Sliding wrist brace:

The sliding wrist brace has FAR more support, including aluminum braces, to prevent your wrist from getting bent backwards when sliding head first into a base.

Are these those wristbraces that many MLB-ers use on the basepaths?

No they are not. I have one of the sliding braces as well. They are 2 totally different things.

Yes, a number of MLB players wear them. Not sure if the Nike model is available off the rack, I use the same thing made by Pro Orthopedic out of Arizona. A google search should yield their info. Cost just under 30 for a pair.

Are they some special compression wristbands? are they sold to the public?
