I have found them here in Texas for $170.00 complete at gun shows. Bought one for my wife and one for my daughter. They love the flexibility, but it has not been cold enough to really test their insulating qualities. I personally use the old extreme cold down-synthetic mix military bag. Spent numerous nights under the stars without tent or tarp in 20 deg. F, and stayed warm. The two drawbacks are the weight, which is around 10 pounds, and they are not waterproof. The Wiggy bags sound good but reviews have been 50/50. Wish Doug would do a test. Then we would know the truth.
