Frequently asked questions
- How is this printed and shipped?
- Every BoomerProud item is printed to order through our US-based fulfillment partner. Production takes 2-5 business days, then it ships straight to you — nothing sits in a warehouse and nothing goes to waste.
- What's the return policy?
- If something arrives wrong or damaged, we'll make it right within 30 days. Because items are made to order we can't accept change-of-mind returns once production starts, so double-check your size.
- How do the sizes run?
- Our tees and hoodies are classic unisex fits on heavyweight cotton. If you're between sizes or want a roomier fit, size up.
