I got a HBS earlier this bow season. It is pretty bulky, the one I have is wind proof and water resistant. I use mine in my summit viper climbing stand, it's a little tricky getting it on but not bad once you get used to it. I run my harness out the neck hole, with the HBS dropping to your waist at the shot I don't know why youd want your safety harness attaches to the suit in any way. I have yet to have the cold determine the length of one of my hunts. I believe so far it's the best clothing purchase I've made for hunting. I'm looking forward to using it coyote hunting this winter, that will put it to the test. I think it's worth every penny.
