    It's purrr-fect.

    Slip into The North Face 20 Degree Synthetic Hyper Cat Sleeping Bag and you'll be purring all night long. Clocking in at just under two pounds, the Hyper Cat is filled with exceptionally light, durable, and compressible Heatseeker One insulation powered by Thermolite fiber technology.

    The streamlined shape and center zip not only conforms to your body for efficient heat retention, but also reduces unnecessary weight when going lighter is of the utmost importance. The Hyper Cat also has minimal insulation on the bottom in order to maximize comfort and performance when paired with a sleeping pad, while the hood-cinch, integrated draft overlap and draft collar do their parts to prevent any further heat loss.

    • Streamlined, lightweight, and toasty bag for the backcountry
    • Compressible synthetic insulation provides warmth and durability
    • Streamlined mummy shape and center zip save weight and warmth
    • Minimal insulation on bottom helps integration with sleeping pad
    • Hood and draft collar cinch out nasty weather
    • Stuff and storage included for easy transport and storage
    • Item #TNF036C

      A Great Synthetic Option

      • Familiarity: I've used it several times

      I try to avoid down if possible, so I was in the market for a synthetic bag and all the research kept leading back to the Hyper Cat. Other than the synthetic insulation, I was drawn to its weight and packability. I haven't tested its temperature rating, but when I have used it I was plenty warm. I'd echo the other reviews that I wish - for minimal weight gain - the zipper was longer. It can also feel a bit tight, but that's not unexpected with lightweight, mummy bag.

      Hyper Cat

      • Familiarity: I've used it once or twice and have initial impressions

      Things I disliked.
      1. The zipper was hard to zip and was not heavy duty at all. the zipper broke on the first use. The zipper only goes less than 1/2 way down so you have to scoot into the bag.
      2. I was willing to give up some comfort for weight and compression size; however, at 5'7" 33 waist I was constricted.
      Things I liked.
      1. The weight and compression size. Not really sure now to convert liters into inches , so I'll just give you inches. Compressed down the bag something like 6x8 inches.

      In the end I was willing to except the tightness of the bag if the zipper was higher quality. I would not recommend the bag because of the zipper. It is as a shame .

      Great for some conditions

      There are a lot of great things about this bag

      1. The weight for the temperature rating. My previous backpacking tent was a Big Agnes Whalen 20 - which weighs an extra full pound over this, and doesn't pack down nearly as small. At under 2 pounds for a 20F bag, this is really knocking on some ultralight expensive bags, and getting fairly close into ultralight quilt territory.
      2. Packability - It is generally the case that down bags pack down really small, while synthetic bags don't. I don't have a down bag to compare to, but this thing packs to almost the same size as an inflatable Klymit static V insulated sleeping pad! That's really small.
      3. Synthetic - down if it gets wet - which need not be from rain - from just precipitation, can lose insulation. For this reason, and since not all down stuff is made responsibly, (down comes from Goose feathers, you know.) I prefer synthetic. P.S: Treated down is getting better and better.

      There are also a few 'not so great' things about this bag.
      1. The zipper does not go all the way down, but this is a good thing in freezing temperatures, since it should retain more heat. In terms of comfort, it could be better.
      2. For some reason, there are loops only on one side of the bag - I get that this is enough if you want to hang it to dry or just generally. But this is a bummer if you want to tie your sleeping pad so it doesn't slip. having loops on both sides would have been helpful.

      Overall for the purposes of a below freezing temperature synthetic bag that weighs < 2 pounds and packs down small, you can't beat the value of this bag for ~ $175.

      If you have a little more to spend the Hyper Kazoo might be a better bag.

      North Face Hyper Cat

      • Familiarity: I returned this product before using it

      I have a Cat's Meow sleeping bag that I've used for years and love. I was excited about the Hyper Cat mainly because it's 1 lb lighter than the Cat's Meow. The quality of construction and materials is consistent with what you expect from The North Face.
      I'm 6'0" 190lbs and I purchased the Regular size. The legs are more tapered than the Cat's Meow but it was comfortable. There was adequate toe room at the bottom. The length of the regular seemed too short for a 6' person. The hood was uncomfortably tight on my head. This bag is also very tight around the shoulders. I had difficulty closing the zipper due to the tightness. Once it was zipped up, there wasn't a lot of space to move my arms. I tried several times to get comfortable in the bag but It was too tight.
      I returned the bag because it wasn't a good fit for me. This bag would be good for someone under 5'10" and of slight build.

      Which compression bag should I get for this sleeping bag?

      Hey there Vernon! The stuffed dimensions are stated in the tech specs as 8" x 14". So as long as the stuff sack has those dimensions it should fit.

      For instance, the Alps mountaineering Compression Sack would need to be a medium.

      Any compression sack that does not give a measurement in inches, a size of 12L+ will work. Such as this one, the 15L would be the best bet

      Hope this helps out!!
