My son is 13 years old and very slim. I have been hunting high and low for a pair of copping jeans that fit and at a sensible price as he’s growing so fast. These copping jeans aren’t perfect but they will do. The legs are slim fitting but they still flair at the waist. The adjustable waist helps but it does create uncomfortable rouching around his waist. The saving grace of these copping jeans is the pants up. This is not fixed in place and can be rolled down to provide enough length.
