I want to thank everyone for their responses. I have not been on the forum in a while. The waders would be used for duck hunting. About the coldest weather I hunt in would be in the 30's. I am thinking about trying some stocking foot waders next but thought I might try ordering some custom waders. I do not use chest waders very often as most of my duck hunting is on levees I access using a boat and hip boots or knee high boots work fine there. The waders I use now are neoprene.
