Five Star Gift Ideas

That's great! Here are a few Father's Day gift ideas for your grandpa who loves roller derby:

1. Custom-made Roller Derby jersey: A custom-made roller derby jersey with his name, number and favorite team colors is an awesome and thoughtful gift that will show your grandpa you know about and appreciate his interests.

2. Roller derby tickets: If your grandpa hasn't yet attended a live roller derby bout, then gifting tickets for him and a friend to attend one of his favorite teams' matches would be an incredible surprise. Make it a fun day out by going with him as well!

3. Roller derby-themed merchandise: And if your grandpa is already a regular attendee, you can never go wrong with gifting some additional roller derby-themed merchandise such as T-shirts, hats, stickers or even a mug with his favorite team's logo.

4. Roller derby gear: Does your grandpa play roller derby or love to skate for fun? Gifting him with a pair of new skating gear such as knee pads, elbow pads, or a helmet would definitely be appreciated.

5. Roller derby book: Finally, if your grandpa enjoys reading, you could get him a good and interesting book about Roller Derby such as "Roller Derby: The History and All-Girl Revival of the Greatest Sport on Wheels" by Catherine Mabe or "Sisters in Arms: British & American Women Pilots during World War II" by Helena Schrader - both have great reviews and positive feedback.

Or you can get him a star map with an important date you share.
