textiles experts, what fabric are these shorts made from (pics)?
about same thing behind cat cat back behind axle axle and back
cat back is everything behind the catalytic converter pipe / muffler / tail pipe / resonator axle back is the tail pipe around the rear suspension to rear of vehicle
Could it be a suede cloth, moleskin or doe suede? If so, the fabric would have one side that was brushed, and feels almost suede-ish. Typically a fairly heavy draping fabric -- I really can't make out much from your photos. These fabrics come in all sorts of qualities. some looks really velvety, and some looks cheap.
