Newly Updated Design
Updated Late July 2022
New Features include:
Dual Differential Cut option
The outer shell is wider and longer than the inner. This allows you to press your knees, toes or elbows against opposite sides, tensioning the inner layer in the process, but without fully compressing the down like you would with a non-differential cut quilt.
Updated Pad Attachment System
The Diamondback’s new Pad Attachment system now uses the widely popular center-release buckles (aka wafter clips) and 5/8″ elastic webbing. Comes with one straight strap and one looped strap and has 2 clips on each side of the quilt.
New WideMouth Footbox option
In addition to sewn and zipper/drawcord footbox options we now offer a Widemouth option. For this option we have changed the shape of the sewn footbox end-panel from a circle to an optimized oval-ish shape. The foot end circumference measurement stayed the same at 42″, but the new shape has a significantly wider diameter allowing for more foot splay, bigger feet, more space between your ankles… a much roomier feeling footbox in general. If you have a foot size that is US size 10 or under and want a snugger feeling footbox option, select the “Round” footbox option instead. Just like before the Zippered/Drawstring footbox option comes with an attached down draft plug to seal the cinch hole.
New Down Options
We are offering both 900 fill Ultra Premium Goose down as well as 850 fill Premium Duck down. Both products are RDS certified and are treated with PFC free HyperDry DWR.
Fill Weight changes
Slight increase to most fill weights. The fill amounts are generous resulting in conservative temperature ratings. Overfill options are still available for those wanting more. Fill tolerance to within 5g of the advertised fill weight
We moved the dual neck shockcord adjustment points from back behind your head, up slightly closer to your ears where they are easier to adjust.
The Short now fits a user 5’9″ and under, the Regular fits someone 6’1″ and under and the Long 6’5″ and under.
Some features were great just the way they were and remain unchanged from the first generation, those include:
The Diamondback keeps the same 50″, 55″ and 60″ width options. For reference, the 55″ wide model will be 55″ wide from about your elbows to just past your hips, from there it tapers slightly toward the foot and head ends(compound taper) The 55″ option adds a 2.5″ wide baffle onto both sides, while the 60″ adds a 5″ baffle to both sides, this extra pair of baffles runs from the top of the quilt to just above the footbox gusset and is tapered. By adding extra width only where it’s needed these side baffles are shorter and lighter, giving you extra width with less weight penalty.
15d Ripstop Nylon Quilt fabric in a variety of colors with PFC free/C0 DWR. This fabric is an absolutely awesome combination of light, durable, and comfortable. Camo options are printed on a very slightly heavier 20d Polyester ripstop fabric that also makes for a great quilt. If you are ordering an Original cut quilt and are interested in any of the 10d fabrics (only those shown in our custom underquilt section), simply select the 15d version of the color you want and let us know you want 10d using the order notes at checkout, then immediately contact us via email and mention it as well.
Included stuffsac (0.5oz-0.85 oz) plus a Large Mesh storage bag
ASE Adjustable Side Elastics. (elastic shockcord and cordlock on the quilt’s long sides to make sure it stays tucked under you). This has been a super popular option for both hammockers and ground sleepers alike, it works so well that for some people it alleviates their need for the pad attachment kit
Draft Collar option
We offer an optional tapered draft collar. It tapers from low profile behind your head to nice and extra fat up front where you need it. You can simply flip it to the inside of the quilt if it’s not needed.
The Diamondback uses our unique Constriction-Point Baffle pattern that uses a series of constrictions in the baffle pattern to isolate both halves of the quilt. The baffle wall height remains the same, but the width of each baffle abruptly merges to a constriction point, effectively breaking a single 6-foot long baffle into two 3-foot baffles, resulting in one of the shortest effective baffle lengths in the industry. A shorter baffle means the down has less room to shift so it will take you less time to fluff and even out the down before each use. The down in the upper part of the quilt stays in the upper part and vice versa. Down can be manually forced through the constrictions but it will not pass through on it’s own, this means the distribution of down between the lower vs. upper chambers stays consistent with use and can be manipulated by the customer if desired. Since the upper and lower chambers are filled independently of each other, overfill can be installed into either the upper or lower chambers or split evenly between them.
Made to order as well as in-stock options available.

Just got my diamondback 20 degree in forest green and autumn orange, wide and long. Also received my Wookie underquilt. This will be my sleep system on my AT thru hike starting in a few weeks. I will be trying it out tomorrow night with my warbonnet blackbird XLC and am sure I will love it. The quality is superb. I have a few 15 degree bags from Nemo and marmot and can see right though the fabric in spots. Not so with the DB quilt. The down seems to stay where it is supposed to. The fit is perfect (although I would have opted for a larger foot box if they offered one. My size 13s fill the footbox abandoned don’t leave much room for down booties/socks in cold weather). This is my first quilt, but I can’t imagine wanting anything anything more. Well done Warbonnet! My entire sleep and shelter system is now warbonnet and I could not be happier.
Just received my 20°+2 oz overstuff. Super light and warm. Slept with it the last couple nights paired with my 20°+2oz lynx full length only got down to high 30s and I was way to warm. Can’t wait for hunting season to test the temp rating. Can’t go wrong with warbonnet
I ordered the 10 degree version. Or rather, a blemished 10 degree with side elastics and it is fantastic. Combining it with the wookie in my wbbb on a cold winter has been pure bliss. It’s light, it’s warm, it packs up nice and tight. My cat loves it too, which is unfortunate because my cat isn’t declawed. What is fortunate is that the material put up with his abuse , at least until I put a stop to his claw-sharpening and threw him out of the hammock. Yes, I do go camping with my cat. No, it is a perfectly normal thing for me to do, especially when it is in my own yard. Please stop judging me, I love my felines and I will not tolerate your unspoken abjudications! They don’t snore, they won’t betray you, argue about politics or threaten to stab you in the middle of the night…
Anyway, the quilt is great. I was wondering where the blemish was so I sent an email. Even after Brandon pointed it out, I could hardly see it. So if their “defects” are top-notch, just imagine how much greater the unblemished product will be. Definitely worth the purchase.
Just a quick THANK YOU! Did a section of the AT last week with my new quilt……ABSOLUTELY PERFECT! I own quilts from two other manufacturers and there is no comparison. Those side elastic straps are amazing. Also, I never had to work the down into the correct spots, it stayed where I wanted it. I’m ultralight at a 6 lb baseweight with my Zpacks Nero and their Plexamid, my Thermarest NeoAir. The********* was on my radar before I discovered Warbonnet, and am so glad I did! You have an excellent quilt in the Diamondback and I’m extremely happy that I purchased it. My son’s Diamondback just got delivered a few days ago! Thanks again!

I ordered a custom diamondback with some of the optional features in a long size, and I love it! Couldn’t be happier with the design, warmth, and colors. Well done again, WB!

Got two quilts, one 20 degree with sewn footbox 55w with 850 goose down for my son and one 10 degree with sewn footbox 55wide with 950 goose down +2 Overstuffed. We love them!!!
Got my 20° DB with sewn footbox in Autumn Orange (15d). This is my new favorite design! I love the footbox. It’s pretty impressive how the seams that are usually behind the calves are completely hidden with no sewn thru seams. The gusset right behind the knees is well done too and placed perfectly just shy of the knees. If I turn the quilt inside out, it looks virtually the same! It looks like it was built to last and look amazing at the same time . Definitely another classic WB product with all the usual clever design choices.
