So far, its been a great cooler. Does the job of keeping beverages cold without transfering temperature to hands. My Flex 15° with one ounce of overfill however exceeds expectations! When I first learned of quilt camping I knew it was for me as I cant stand feeling cocooned into a standard bag and usually leave them unzipped. After months of searching and comparing I ended up with the Katabatic. I have only used it once and absolutely loved it! So soft, with so much loft. Used a beanie and neck buff and did not close draft collar until below 30°. I look forward to years of use. Now in the market for a hood. I have found a couple others that may work, yet with my initial Katabatic experience I would rather wait for their product to become available again as I know the quality is top notch.
