The edition size is the number that counts. A tee numbered 1 out of 50 is more collectible than one numbered 1 out of 5,000. When you're evaluating a Windbar limited edition tee, look for the total run size. It's usually printed on the tag or on a separate certificate. If it's not there, ask.

Also, check how the number is applied. Is it screen-printed, embroidered, or on a woven label? Printed numbers can fade over time, which hurts the resale value. Embroidered numbers last longer and feel more premium. A woven label is a common choice for official limited editions because it's durable and harder to fake.
