These trousers are a lovely blend of wool, silk, and linen. Don't let the word "flannel" on the VBC fabric mill confuse, these are not typical flannels only meant for cold weather. in fact, I have worn them in the summer, and they do just fine. Details include beltloops, button side adjusters, and a hook and inner button closure. The inner button hole has been reinforced, but other than that these are in EUC. Please contact me with any questions, and offers are encouraged!
