Sustainability

Why yes, we do think it matters. It matters a lot!

From the fine details to big picture goals, we know our decisions about materials, partnerships, and daily operations can have far reaching effects outside this building. Climate change affects us all. It is personal. We have more progress to make, but here are a few ways we currently prioritize sustainability.
1. Reduce demand for raw materials
2. Reduce the use of harmful chemicals
3. Reduce our carbon footprint and waste in landfills
While Katabatic Gear is committed to making UL gear that exceeds your expectations, it is equally important that we minimize our negative impact on the planet and its occupants. Whether it’s a special place in the backcountry, or the city you live in, we want to do our part to maintain healthy land, air, and water to keep this a comfy home for all. Though ours is not a perfect plan, we will continue to search for ways to improve our sustainability efforts, and minimize the impact of our operations on the planet.
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.
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 Eco Ripstop (.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. 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 Taffeta (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.

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!

Alsek Wide

Great quilt. I was torn between the regular and wide but went for the wide in the end for extra comfort (despite the weight increase). Build quality is fantastic and quilt feels very warm on the limited nights I've used it so far. Highly recommended.

Alsek Quilt Lives Up to its Name!

My son has already slept outside this winter in his Alsek Quilt and loves it! He's looking forward to many camping trips with it.

My all time favorite gear from a gear junky

I got my Alsek 22 in the fall of 2016. I just got back from Northern Michigan in November 2021 and I still love this quilt. I have spent over 300 nights in this quilt and it has never let me down. That said I wish I got the 30 degree bag because I am a hot sleeper. I have used this quilt down to the mid 20s (-5c) and never gotten cold, and I sleep in the buff. I have woke to 4" of snow on the tent, freezing rain, frost on everything and I was still sweating lightly in the Alsek. I have never used the strap system and actually cut the connectors off because I haven't found I need them.

I am a gear junky that is not very cost conscience, I am constantly buying and trying new gear. In the last six years there is only two pieces of gear I have not considered replacing. #1 My Zpacks Duplex, #2 my Katabatic Gear quilt... well actually I did get a 40deg Chisos for summer use because the Alsek is too hot above about 45deg.

Only negative I can see is no option for customization other than more down fill. I would love to be able to buy one without the strap system, but that will not stop me from buying another Katabatic quilt. I will just cut the connectors off when it comes in the mail.

Fantastic

Of all the backpacking gear I have, my Alsek is the single best item. I’ve used it for over 3 years now, on numerous overnight and longer trips from Appalachia, to the PNW coast, Glacier NP, Maroon Bells, the Winds, and the Pemi Loop. I’m usually in a hammock, but I’ve also used it on the ground. When it’s colder I use the snap, which causes the quilt to nicely snug up around my shoulders and back. I’ve not used the pad straps. If I was on a pad more often I might, but so far it hasn’t been necessary.

The design and craftsmanship are excellent, and the materials and sewing have held up outstandingly.

For comparison, I’m 6’ 4”, 250 pounds and have the long, wide version.

Like I said, this is the best piece of gear I own. And that’s not for lack of having a well stocked inventory.

Excellent Quilt

I've had my Alsek quilt for about 18 months now and used it on, I think, 4 trips / 10ish nights so far. (Fewer than I'd have liked, but, ahem, pandemic.) Therefore I figure I owe a review. TL;DR version: I highly recommend this quilt.

I've used the quilt in tents with and without a partner, with lows mostly in the upper 30's and lower 40's. Fortunately for me, weather on all these trips was great, but that does mean I've not pushed toward the rating of the quilt yet. That said, I've been very warm every time and had no trouble with drafts or cold spots. (In the 40's I'm almost too warm; I have to go hatless to vent some heat!) Impressively, the quilt stays snuggly on top even when I don't bother to use the pad straps (which, at these temps, is usually) or fasten the collar, whether I'm back, stomach, or side sleeping. In short, I've been plenty warm just sort of flopping it over me. This gives me confidence that it will perform down to 22°F as rated if I were to bundle up a little more.

The quality is very high, and no down shedding yet (unlike a competitor's quilt I've owned). The fabric is soft. Weight was as advertised and compression is good. The only thing I regret is that mine is brown, and now they come in the niftier blue color. :)

For reference, I'm 5' 11" and bought the 6' 6" regular version. Plenty of room without dead spots. (I sized up for stomach sleeping. I probably could have gone with the 6' version safely but I don't regret the extra length.) I'm skinny, so I typically sleep a little cold. This quilt is the first sleeping bag I've owned that, for me, seems to have a correct temp rating.
