Durable and warm.  I washed it a few times to help break it in.  I especially like how it zips up to the hip, making it easier to go on over your boots.  I am a waist size 36.  For insulated overalls, make sure you measure your waist with your winter clothes (pants and undershirt) on, or at least your jeans and belt on.  I ordered a size 44, which leaves several inches of room to move to move comfortably with some additional space.  Do not order inseam size longer than you need, it would be difficult to hem these.  My inseam is 30, but it seemed a little long.  I ended up hemming the shoulder strap to keep the pants from dragging around the heels.
