Thanks much for the response to the IWOM - seems quite a few people have used the HBS and not nearly as many have use the IWOM. I'm not a fan of having to "remove" myself from the HBS for a shot that is why I'm leaning towards the IWOM. That being said - a couple of questions I had - how cold have you sat in the IWOM and been comfortable? Late season hunts here in MN can be near 0 so I want something that will keep me warm. Also, how is it have your feet in and enclosed "sleeping bag" bottom, does it hinder moving and/or turning to make a shot. How is the overall bulk of the IWOM - doesn't seem nearly as bulky as the HBS which greatly intrigues me as well. Like I said, hard to find a lot of people that have experience with the IWOM as opposed to the HBS. I appreciate your help.
