The Fatigue Pant from Engineered Garments might be one of the best pants ever made. We think so at least. They take inspiration from classic military "baker pant" style fatigues. These have an excellent loose tapered fit, with plenty of room through the seat and thigh with a slight taper to the ankle. Other details include a hidden internal waist button, Talon zipper fly, internal drawstring and a hidden zip pocket behind front left patch pocket.
