I'm also looking to get a box blind this year. It's between the Redneck and Shadow Hunter and leaning Shadow Hunter due to the reviews of guys on here. I want to look at them at the Deer & Turkey Expo.
My wife and I both have the HBS. It's, in my opinion, the best piece of hunting gear we own. My wife is small and she does multiple sits during the rut and rifle season with it. I like I can wear very little clothing and stay warm during those same timeframes. The worst part of the HBS is getting out of one to walk back to the truck!!
We were at the pro shop one day and a guy was looking at the HBS and talking about how he gets cold. He asks the owner about how warm they are and he looks at my wife and says ask her what she thinks. My wife tells him how much she likes it and the days she sat all day with it. He looks at the suit, again at my wife and says I'll take it. If it can keep her warm, I should be good. About three weeks later we're back at the shop and the owner tells us the guy came back and bought another one for a family member.
