I got tired of buying cheap backpacks in school every year and bought my son a Sand Piper backpack in middle school.
Hes graduating from college and still has that same backpack and uses it every day. There was an issue with some stitching and I sent it back to them and they wanted to replace it. It was the USMC digital pattern which was no longer available so they repaired it. I think he had the three day pass.
