Depends what you are looking for. If you want support, Dakine makes a pair, and there are many others do as well. There is also support built inside gloves like the Burton Impact line.
If you're looking for preventive and especially if you've broken/fractured your wrist in the past like I have, I would suggest you look into OTS wrist braces which literally stop your wrist from hyper-extending back based on what type of degree of freedom stop you install on it. They're pricey but they're worth every penny.
Government - If you think the problems they created are bad, just wait until you see their solutions.
