If using a New River UQ,,,which is synthetic over down,,does anybody use a waterproof protector from like 2QZQ? over their quilt? in windy/very blowing raining hikes? Or does the fact that the UQ is synthetic made vs. down,,it really doesn't need it? Just curious so I thought I would ask,,as in reading the down quilt manufacturers,,I find alot of guys are using a protector of some kind to keep their down from getting wet even tho outer material is DWR finished.
