Vintage Filson Pants Men 40x31 Green Chino Poplin Style 55 Tin Cloth 1960s/1970s

These are in excellent condition and have no major signs of wear, they appear to have been hemmed at some point judging by how they are sewn but I could be wrong. The two back pocket buttons have also been re-sewn. From either the 1960s/70s but I’m more so leaning towards them being from the 60s. Measurements: Waist-18.5” Inseam-31” Thigh-14.5” Knee-11.5” Leg opening-10.2” Front rise-12.5”
