my revit sand 3 this is xl i am asking large in most things always xl in revit jackets they size small no back protector but there is a pocket in the back for one in good solid order the thermal liner never worn the removable waterproof liner has some marks on it where it was left in my top box some water spilt out my bottle onto a spanner and it ended up with some rusty marks pictured again I've never actually used it because I avoid rain where possible and have a revit rain jacket that goes over the top of anything , please see all the pics
