I know this is an old thread but wanted to comment after a year and a half of use with my Wiggy's bags. They have been amazing! They are literally the most comfortable bags I have ever slept in. I have had quite a few bags over the years (multiple North Face bags, multiple Marmot bags, Rei, Ray Way quilt, Western Mountaineering, Enlightened Equipment quilt) and am seldom truly comfortable when sleeping. It seems I am usually too hot or too cold, or too hot to begin with then cold around 4am. The quilts come in second comfort wise to me. For some reason the Wiggy's bags have a wider comfort range for me than other sleeping bags. I don't overheat and sweat as much and thus stay warmer. Kinda gross but when I wake up the exterior shell of the bag is slightly damp around my core, I wonder if the lamilite pulls the moisture away from my body better than other bags. They are like a warm poofy cloud that seems to be just the right temp. If you read through my initial posts you will see I wasn't too happy with my purchase to begin with. These bags are still big and heavy, but they make up for it in comfort and reliability in my opinion. For the first year I kept telling my wife how comfortable the bag was and after her first night sleeping in it she completely agreed and I no longer had a wiggy's bag. I just ordered a second superlight FTRSS combo. I've read through many of the posts where the wiggy's owner rubs me the wrong way and I get his newsletters where he attacks other products which also rubs me wrong, but bottom line on the sleeping bags I own is they are amazing and are what I use when the conditions are right. Just wanted to share since these forums is where I go when looking for info.
