I recommend always wear a helmet while riding. You never know what could happen. Someone could hit you, especially when the slopes get crowded. A simple edge catch could mean a whack to the head. One time I was just cruising down to the lift at the end of the day and visibility had become pretty bad. Was on my toe edge and hit an unexpected dip in the contour of the snow (like thinking it's the last step of the stairs when it's not). It jarred me pretty good and caused me to catch my heel edge, hitting my head violently on the hard snow. Luckily I was wearing a helmet and rode away with some whiplash and a little embarrasment.
Also, wrist guards are a good idea. Wrist injuries are the number one injury in snowboarding. I haven't worn them in the pass, but I will this year, especially since I plan to work a lot more on spins.
