These overpants were inspired by the design of Sasover Trousers from British Army in the 40s . The monotonous pattern and the poor fit of the waist have been tuned . There are two tucks in the waist to maintain the volume around the hips , while flat elastic is used to improve fit . The material is a finely woven moleskin stretch with fine suede brushing , giving it a soft texture and warm feel. It is a botanical hybrid piece dyed .
