Not if you are air boarding
I'm going to Aspen for the first time in a few weeks.
I've never been snowboarding before.
I'm just trying to figure out what I really need to buy before my trip....
All joking aside who will have a fun time at any of the Aspen mountains you go to. What you really need is to already planned to take a lesson and rent gear. Rental gear usually is available for boots, bindings, board, and helmet. That leaves, goggles ( a must), neck gaitor or neck face mask, Gloves or mittens, Jacket, snow pants, first layer clothing, ski/board socks, sunscreen/chapstick and tip money for the instructor.
Optional Items: wrist braces, butt pads( I have never worn nor needed),
P.S. you might be able to rent most of the outwear too.
