I will give the HBS the best compliment I can give a piece of hunting gear, if I lost it or "broke it" tomorrow, I would immediately get another one.
I have converted my friends now. They wondered why they waited so long and froze so often. This is coming from diehard Wisconsin bowhunters in their mid-forties.
Regarding limiting your hunting ability, I would say absolutely the opposite. You can sit longer and warmer so you muscles are more limber and when you do shoot, you are not wearing some bulky jacket.
And Whip, it is very quiet.
I do one added thing with mine. I have short backback bungee straps that I wrap around each leg at about boot height. It makes moving the feet easier in stand.
