I love it!
I love the Primos vest because it allows me to have a place for everything. No more searching around for my rangefinder or windchecker. I know right where everything is and can get to it without having to take off a pack. Often times I don't wear a daypack anymore. Everything I need is in the vest. Sometimes I'' wear a very narrow hydration pack which has room for my raingear and lunch.
So far I've converted my hunting partner and one game officer who saw the vest and loved it. One tip would be to buy it big enough to wear over raingear or layering you want to do. You don't want all your gear under several layers of fleece when you need something.
