  • Responsibly Sourced Down

    Like many of our customers, we at Katabatic Gear are concerned with the environmental and animal welfare impact of our products. We are dedicated to a responsibly sourced, and very high quality product, just like our down supplier, Allied Feather and Down. They are certified through both the bluesign®and Responsible Down Standard®programs. Another reason we partner with Allied: we can offer our customers access to the Track My Down program. It allows our customers to learn everything there is to know about the down in their specific quilt. For more information, please follow these links to Allied’s Pledge, FAQ’s, and Track My Down pages.

    900 Fill Power Goose Down

    We use the highest quality 900 Fill Power goose down, offering the most loft and warmth for the least weight. Goose down has many advantages over synthetic insulations. In warm temperatures goose down allows heat to pass through, giving it a wider comfort range than synthetic insulation. The down can be intentionally moved around in its baffles, allowing you to adjust the amount of insulation based on conditions. Finally, synthetic insulation breaks down more quickly with use, losing loft and warmth. As a result a down filled product has a life span many times that of a synthetic filled product, making down a much better value. Our 900 Fill Power premium goose down is produced for us here in the U.S. by Allied Feather, and is available untreated or with HyperDRY™ water-resistant treatment.

    850 Fill Power Duck Down

    With all the benefits of down vs. synthetic, duck down is often cheaper than goose down, only due to the fact that it is more widely available. For years it was difficult to obtain duck down in a fill power greater than 700, which meant a heavier sleeping bag. Now that we can get responsibly sourced, high quality, 850 f.p. duck down, we are happy to be able to offer it to our customers. There are no quality, performance, or longevity sacrifices in buying a duck vs. goose product. One potential downside is that the natural animal odor that can be present in down products is more common to duck down than goose. This does not mean your duck down will necessarily have an odor, or that goose down will not. It varies from one lot of down to the next, and we’re told it is due to the birds’ diet. Some folks don’t notice any odor, while those more scent sensitive might, particularly if the bag is damp. As one customer put it, “Who cares! In a week or two it’s going to smell like MY odor.” Our 850 Fill Power premium duck down is also produced for us here in the U.S. by Allied Feather, and is offered with HyperDRY™ water-resistant treatment.

    HyperDRY™ Water-Resistant Down

    We are pleased to offer HyperDRY™ hydrophobic down. This down has been treated to provide additional resistance to unwanted moisture. In conjunction with our highly water-resistant shell materials, HyperDRY™ provides extra peace of mind, and dries faster than untreated down if it does get wet. Is this a miracle water-proofing that will allow you to sleep out in the rain or dunk your bag in water with wild abandon? No. Will it give you extra protection and help maintain loft in damp conditions? Absolutely! Our water-resistant down is bluesign® approved, so you can rest assured that it is safe for the environment and human health. Produced for us here in the U.S. by Allied Feather. Available in 900fp goose down and 850fp duck down.

    The softest fabric you’ll find for the liner of an ultralight sleeping bag. This Pertex Quantum plain weave makes for a silky soft liner fabric on the inside of our quilts. We get tons of customer feedback stating that it’s the most comfortable sleeping bag fabric to ever brush up against them – not as clammy or crinkly as other fabrics.
  • Quilt Style Sleeping Bag

    The idea behind a quilt style sleeping bag is to eliminate the insulation from the bottom of a conventional sleeping bag. Why? Insulation must have loft and trap air in order to be effective. Since any insulation beneath your body gets crushed, it is wasted. So why not leave the insulation (and the fabric and all that weight) out of the bottom of the bag? This is what a quilt style sleeping bag does, but it goes one step further.

    When a quilt style sleeping bag is designed well, versatility is significantly increased. Our patented pad attachment system and elasticized edging keep your body heat in and the cold drafts out. When conditions are warm, lay the quilt over you like a blanket and allow some ventilation. There are numerous variations in between, making our quilts comfortable in a much wider range of temperatures than a traditional sleeping bag. Another huge benefit of a well designed quilt: you can toss and turn and roll around without getting tangled up or rolling off your pad!


    Attachment System

    The backbone of our down quilt style sleeping bags is our patented Cord Clip attachment system. The beauty of this design is its simplicity. All our bags feature our Cord Clips, and come with 2mm cord for attaching the sleeping bag to the pad. Simply cinch the cords around the pad, and attach your bag! This system works easily with most sleeping pads.

    Our Cord Clips feature two attachment options for maximum versatility. The first attachment position allows the clip to slide freely on the cord. For warm weather this gives you the most freedom of movement. As the temperature drops, clipping into the second position allows you to lock the bag in place on the cord. In this position you can control the girth of the bag, and are able to set the bag to overlap your pad to lock out drafts. Even with the Cord Clip in this position, adjustment along the cord is easily accomplished by lifting the Cord Clip vertically. With the Cord Clip held vertically it slides easily along the cord. Returning the clip to its horizontal position locks the Cord Clip in place along the cord. This allows you to adjust the interior volume of the sleeping bag, as well as adjust the bags position on top of the sleeping pad. Secondary clips help seal out drafts when the temperature really drops. This unique design offers significant advantages. The ability to attach your sleeping bag to the top of the pad, as well as the ability to easily adjust the girth/volume of the bag, allows you to optimize the position of the bag depending on your sleep position, and the level of warmth you need from your bag. In warm weather you have much more room than you are used to in a mummy bag. In cold weather just close the bag in around you for maximum warmth.

    We have engineered our Cord Clips to be strong and durable, while being thin and unobtrusive. Even if you have your sleeping bag pulled in under your body, our Cord Clips are designed to lie flat and to be unnoticeable. Our Cord Clip system is fast, simple and easy to use. Attach the cords around your pad before you leave home. Then just lay out your pad, clip your bag on to it, adjust as needed, and sleep!


    Continuous Baffles

    The baffles in our quilt style sleeping bags are continuous from one side to the other. This allows down to be moved to the top, sides, or bottom of the quilt when temperatures fluctuate. On warm nights, you can move the down to the sides or bottom, allowing a little heat to escape. On cold nights, move more down to the top of the quilt to keep that body heat in. This works particularly well when the quilt is attached to your pad, because the same part of the bag is always on top, no matter how you roll, toss, or turn.

    Down Collar

    Our quilts feature an overstuffed down collar around the neck opening. This critical feature means you can comfortably seal warmth inside your sleeping bag without choking yourself with a scrawny drawcord.

    Trapezoidal Foot Box

    Optimized for when you need the most room, lying on your back, our trapezoidal foot box fits great no matter what position you are lying in. Plus we overstuff the baffles over the foot section to provide extra warmth. Our goal is simple: we want you to have warm, happy feet while you sleep.


    Separate Hood

    When you think about it, a separate hood really makes sense. If you toss and turn, your quilt stays in place on top of your pad, and your hood stays in place on top of your head. You are not going to wake up in the middle of the night, lost somewhere in your mummy bag, wondering which way leads out.

    Do you need a hood? Here is what we have found: if temperatures are going to be near the temperature rating of your quilt, then you will probably need a hood. If the forecast calls for warmer weather, leave the hood at home, and just wear a warm hat to bed. Looking to save weight and get the most use out of minimal gear? Take a warm jacket with a hood, and wear that to bed if the weather is cold. You keep your head warm, and add extra warmth to your entire sleep system.

    Bivy Sack in Conjunction with Quilt

    Our water resistant, highly breathable bivy sacks are designed for use under a tarp or floorless shelter. These bivy sacks provide a waterproof floor, full bug protection, and a water resistant upper to protect your quilt from spray and mist. Our bivy sacks are designed to integrate perfectly with our quilts. Simply attach your pad to the floor of the bivy through the pad attachment cords, then clip your quilt on to these same cords. Your pad stays in place in the bivy; your bag stays in place on the pad. Leave your pad attached to the bivy and setup the next night is a breeze.

    The System as a Whole

    What does it all mean? Set up and adjustment are quick and simple. The quilt stays in place on top of your pad. The hood stays in place on your head. All our components are designed to work together, but the system is also designed to make the most of gear you already have. Our quilts can be partnered with almost any sleeping pad you like. Use your hooded jacket or a warm hat on cold nights. Use the tent you already own, or partner our bivy with your tarp. All in all, you are making the most out of every piece of gear, while resting comfortably no matter what position you sleep in.

    The bottom line? Our sleep system is much more versatile than any conventional sleeping bag, and it weighs a lot less!

    This is my 3rd Katabatic Quilt, I also have the Elite series Alsek and a Flex 15, both of which have performed beyond compare in the field for me. I got this one as my new summer quilt and have yet to get a chance to use it in the field, but like all my other quilts the craftsmanship on this one is just as excellent as the first quilt I got from then in 2015.

    The best. I have 2 bags from Kata, this and Sawatch (for real altitude> 5000 and winter). But Chisos is just an everyday hiker stuff up to 4000m , used many times in mild winter conditions (-5C) combining with down socks and hood. Alex, Chile

    Actually I just shipped it back without spending a single night in it so this review might seem unfair. The main reson why I did that was because I found it too thin. I live in Sweden and we use the metric system and degrees Celsius so it was a bit tricky to convert the measurements to something I fully understand. I mostly spend my time in the Swedish mountains in the summer but we can have snowfall in August and the temperature will often drop under the freezing point for water. What I can do tell is that the craftsmanship is excellent ! My only feedback point to work on is the actual colour of the fabric versus the picture in the homepage. In real life the colour was more electric than flat olive. However I will go for the thickets one as soon as a get my refund : )

    In California the High Sierras are a no go for me in the Winter, since Im not a snow type. Im a huge fan of Katabatic since with my Palisades 30 F Ive logged over 30 nights in last 2 years in the Sierras on the John Muir Trail and elsewhere, and also in Death Valley. The Palisade is 23 oz. pack weight for freezing temps, now thats a good deal! Now Im trying to really go Ultra light for warmer conditions, so I was very excited to get my 40 F Chisos quilt. Same high quality as my Palisades, and an incredible 14 oz. total weight (no stuff sack). Just cram it into my tiny UL pack. Shouldnt say cram, because the Chinos pack size is super small, for my small bag its barely larger than a standard Nalgene. I cant wait for my first Southern California backpack next month.

    Katabatic makes fantastic products and I already owned one of their quilts. When I wanted a warmer weather quilt the chisos was top of the list. The craftsmanship is superb and the materials are top notch. The rating seems accurate and as a warm sleeper Im pretty confident it could cope if things dip a few degrees below 40.
