How about getting them a personalized snowboard? You can customize it with their name or a special message, and choose the design they like. Another option is buying them a gift card to a snowboarding shop or an online retailer that sells snowboarding gear, so they can choose their own equipment or apparel. If your friend also likes to read, you can also get them a book on snowboarding, such as "The Art of Snowboarding" or "Snowboarding Skills: The Back to Basics Essentials for All Levels".
Or you can get her/him a star map with an important date you share.
