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.
Pertex Quantum Y Fuse Eco Riptstop (.85 oz/yd)
The best fabric you’ll find for the shell of an ultralight sleeping bag.
1. Keeps your insulation drier: Best DWR we’ve tested
2. Keeps your insulation loftier: Lightweight, soft, breathable, and downproof
3. Keeps your quilt out of the landfill: Pertex Y Fuse technology extends the longevity of this already durable UL fabric, and also improves its highly downproof and water beading properties
4. Reduces demand for raw materials: Eco version of Pertex Quantum is made from recycled yarns and maintains the fabric’s advanced performance qualities
Pertex Quantum Tafeta (1.0 oz/yd)
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!

Differential Cut
Our sleeping bags feature a substantial differential cut, which is highly beneficial in a quilt style sleeping bag with adjustable girth. The shell fabric is cut wider than the liner fabric, making the circumference of the shell larger than that of the liner. This means that when you start to draw the bag in on a cold night, you’re less likely to crush the insulation creating cold spots. This is a detail that many manufacturers overlook, but we think it’s one of the keys to a more effective quilt, and a warmer night’s 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.

Versatile Foot Box
Our zippered foot box features a versatile system that offers numerous options for ventilation, or complete warmth. Along with the zipper, the drawstring, snap, and down-filled draft blocker allow you to decide whether you lock out the cold, allow in a little fresh air, or completely open up to a blanket.

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!

I've used a Sawatch for four years and absolutely love that bag. So plush and warm'it still makes me smile when I crawl inside. This year, for a summer bag on the CT, I decided to go with the Flex 30 with 2 ounces of overfill. Great choice, plus the Flex series is a bit wider which I enjoy. Lots of choices out there for good quality quilts but I still feel Katabatic is the best. It's an investment, for sure, but one that continuously pays off.

Amazing quality. Super warm when closed up. However, I am a hot sleeper, so I love how this quilt opens up fully. Also very light, even with 1oz overfill.

I have owned the Flex 30 for 3 years and it has been everywhere with me. I am impressed with the quality of this quilt and overall versatility. One notable backpacking trip was spent in a borrowed single person tent with poor ventilation on a 28 degree night. When I awoke my quilt was absolutely covered in frost. I did what I could to remove as much of the frost as I could before getting under way but after breakfast and with the sun coming up temperatures were reaching high thirties. I had a long stretch and had to stuff the quilt while still covered in melting frost. After completing my 18 mile leg I quickly removed my quilt to dry it out only to find, to my surprise, it was perfectly dry! So all that to say I am very impressed and do not regret my purchase one bit. Thank you Katabatic for an amazing product.

I have owned the Elite Series Sawatch 15 degree quilt for 2 years now and getting tucked away is my favorite thing about arriving at camp after a long day of miles. I have experience the quality of Katabatic quilts (once you do it is the only way to go) and I needed a spring/summer/fall quilt. The Flex 30 is the answer for me. The versatility is fantastic with the combination of zipper, footbox snap, draft collared footbox drawstring, and many different variations on the sleeping pad attachment system. As a cold sleeper, I can even take this comfortably BELOW the rated temp with the addition of a couple extra layers. for temps of 25-40, I zip the Flex 30 and draw the footbox closed + use the attachment system and draw it in snugly. For 40-50, I zip the quilt, snap the button on the footbox and use the attachment system. For 50-60, I zip the quilt, maybe snap the footbox or leave open, and use the first set of attachments for the sleeping pad, leaving the top loose like a blanket. For anything above 60, I unzip the quilt and lay it flat like a blanket. For nights with a wide temp swing, if I wake up and need to adjust it is taken care of within a couple seconds. I have 2 Katabatic quilts and can be comfortable in any temp ranging from 10-75 degrees. That lets me backpack comfortably year-round in the midwest where I live. Priceless!! Quality is perfection, silky amazing feel, super lightweight, packs down amazingly well, and comes with a bunch of cool stuff! Super heavy duty cotton storage sack, sil nylon stuff sack, a sticker, 2 sets of sleeping pad straps, and straps for cinching the quilt in tight without attaching to a sleeping pad. Love it!
