FOr a single trip you will be fine. Then again, for many trips you will be fine! I have a marin set of bibs, I got in a raffle drawing. For a top, I use either my current or old ski coat.
If you snowboard, I am sure the reinforcements are equal. As both need butt and knee padding etc.
Other than the reflective part of the coats, I really do not see much difference when trying the two coats on. You can get insulated coats for both sports.

I drives me dinghy!
