I said this somewhere else, but I hate taking things in the woods with me in general. So, I most likely pack in less stuff than most (1 bottle of water, range finder, grunt tube, binocs and bow (with release strapped to bow, arrows in the quiver) is it for most trips...add antlers for stands I can see a good distance from). Also, I've never had to bulk up with extra clothing, as I must naturally run hot or something. I can't think of a time I wore more than long johns and a Scent Lok Suit when using the Heater Body Suit. So, that helps cut down weight, as well.
What I did is had them give me the pack they sell for the suit. I got it for free, so I couldn't tell you if it's a great deal or not, but it does work a lot better than the strap system they sell. I just stuff the suit and everything I'll be bringing, outside of the bow, in it. It's a no frills pack, but it's nice to only have to carry the bow. For whatever reason, if I have something in a pack it doesn't seem anywhere near as heavy to me.
