These are the "Bert" shorts from Ottobre 3-2009-23. They feature 4 patch pockets and a faux fly, plus some topstitching.
The fabric is part of what I salvaged from my previous capri pants disaster. Although I like this shorts pattern, I'm not so sure about the combination of lightweight stretch khaki poplin and royal blue topstitching for boys' shorts. At least they will be very cool for summer.
