Seams are well sewn along with added material that is reinforcing the lower butt, crotch area and both knees. I love the slight angle incorporated into the seam on the fly. Great thinking on that one! The weight of the material is perfect, It is tough yet not stiff and the adjustment tabs on either side that allow you to not wear a belt on "casual" Friday  are an added bonus. All around great pants for the price and I would absolutely recommend them to everyone...boys and girls! They do run a bit big but I think you will want them that way given the activities they are purchased for.  Thanks for a superior product .
