Grub: This is how I layer :1st layer thin poly, 2nd poly turtleneck, 3rd core protector it breaths, 4th Back thing kidney belt, 5th bibs, 6th poly jacket, 7th Shell. I don't get cold & shell is saturated with moisture when day is done. Maybe I'm getting lazy but seems to me all but layer 1 & 2 could be designed into a 3 in 1 & all on & all off. You know if fits you when you buy it & everything can zip in & out. Now I have to hang all these & different layers up & gather to put them all back on. I won't get into all the different braces I wear due to prior injuries but I'm looking for fast on fast off & eliminate gathering. Lazy people design faster ways to do stuff. I also think the ladies would rather keep their figures with All in 1 than layer equipment like football players. Woman would rather look good than wear layered equipment protection. Right??
