We have ordered the small regular and the medium regular for my son and both pairs did not fit despite the measurements that we took. We followed the idea of measure twice (or three times) and order once. That failed us because neither pair we ordered fit.

These seemed to be well made based on the stitching and the seems that I saw on the pants we received. The pockets were nice and deep and big. The patterns we ordered matched the pictures we saw on Amazon.

I would just be wary of the sizing.
