has anyone tried the heater body suit for bowhunting? like can you open it quickly and quietly and does it keep you warm in sub-zero temps?

My Highschool Basketball coach swore by the one he used. I like the concept, but seems to be just another bulky thing to pack in and out of the woods. I'll stick to the Under Armor Cold gear and good layering untill I hear more about the heater body suits.

My dad has one and he loves it. it may be bulky but its better than freezing ur butt off on those cold winter mornings. its kinda neat cuz the zipper is on the inside so u can unzip it quickly and quietly. its worth the money

To bulk for me. I am need a tariler for all the things I haul in the woods.
