Hello Tye, thank you for taking the time to review our Garmin band. Currently, we are using Horween leather, probably the best leather out there. Thickness has been tested and proven to work on all our bracelets and other watch bands over the past 7 years. Also, the remaining leather should be trimmed off. The directions are on the craft paper watch place holder that came with your band. Please feel free to contact us directly to discuss that process, or if you are wanting to return your purchase.
