An Elite series turkey vest works great for most any type of hunting. It comes with a drop down seat that is heavy, but you can zip it off, and what is left is a garment with all the pockets you could ever need, including a blood- proof game bag.

If you can find one made of nylon, it will weigh only a few ounces, but have enough pockets for most any activity. When one gets worn, I retire it from turkey hunting and switch it to another activity. I have one that I use for wade fishing and I just leave all my gear in it between trips; never have to look for my tackle.

One drawback - all I've ever seen are some type of camo and that may not look too cool for some activities. I long ago quit worrying about cool, so it's no issue for me.
