I wear wrist guards snowboarding (as does everyone else who knows you should).
I have Dakine ones, they have rigid section that goes around the underside of your wrist and into your palm. This can be a little restrictive as your wrist is kept slightly bent but you get used to it.
They’ve recently released a new version where the rigid section doesn’t extend into your palm, i can’t comment how good they are but friend has just bought a set so will know when we go away in December.
FYI, I broke my wrist while wearing wrist guards a couple of years ago, completely snapped my radius at the point where the wrist guard ends. The nurse in the Alpine health centre told me that you’ll break your arm anyway if you land hard enough, wearing a wrist guard will force the break further up the wrist which will be cleaner and easier to heal. Without a wrist guard, the break will happen in the weakest spot, which is right in the wrist joint. This will often result in serious and long term issues in the wrist.
This theory is corroborated by the experiences of a friend of mine, he forgot to wear his wrist guards one day and broke his wrist in the joint. Pretty much shattered the end of his radius and ulna bones, resulting in having to wear a wrist brace for years. He still can’t bend his wrist properly. He’s a chippy and ever since he broke his wrist he hammers with his whole arm rather than bending at the wrist.
As my break was clean it healed well, there was a chance that i would need metal pins etc, but it wasn’t necessary. My wrist is as good as new now
