I bought this great bag for a trip to Idaho this Sept. For mule deer and elk. I have used this 3 or 4 times on local outings and it was a huge upgrade from my north face meow bag. The Vortex bag is so comfortable and the zipper and velcro closures near the top really seal out cool air to keep you nice and toasty. Thanks Browning for a great/ affordable bag. Bag packs up reasonably small to carry in my mystery ranch beartooth bag. I can't wait until fall.
