The Sierra Stealth is a wearable summer down quilt — wrap up in it like a serape on a cool desert or alpine night, then form the footbox and sleep in it as a top quilt, in a hammock or on the ground. Comfort-rated to 40°F, it's our lightest wearable: a sew-through (non-baffled) build that trims weight for warm-weather camp and trail, with easy venting and no squirming to get in and out.

Designed for the ground sleeper, it runs wide — 55 inches at the shoulders and hips to eliminate drafts — then tapers to 45 inches at a lengthened foot box for better tuck control. Six side lacing tabs secure it around a pad, and a non-snagging hook-and-loop head hole lets you wear it as a serape and re-seal it cleanly. A long version (86 inches) is available for campers over 5'10".

Shell & down: 850 fill power, RDS-certified, with an Activ-dri hydrophobic treatment that keeps the down drier, behind our wind- and water-resistant Ion 1.1 shell. (Activ-dri is still down — protect it from direct soaking like any insulation.) Over-stuffed 25% by weight to reduce down migration and hold its rating between cleanings.

Footbox: Formed with a drawcord, cord-locks, and double-sided Kam Snaps — leave it flat as a blanket for venting or cinch a foot box.

Stacks with other quilts: Any Big Meadows or Wearable quilt of the same length snaps to any other, so a Sierra Stealth 40° layers with a Sierra Sniveller 20° or a Big Meadows 20° into one system — and nothing stops you adding a third. Any temperature combination works, multiples of the same rating included, and there is no limit on how many you stack. Quilts made from 2019 on have the snaps; before that we used Omni Tape, which doesn't stack.

Compression sack: Sold separately (many campers now keep quilts dry in a contractor or trash-compactor bag instead). For 40° quilts we recommend the large size.

Regular: 78 inches / 18 oz. Long: 86 inches / 19.5 oz. Hand-sewn in Pennsylvania. Sleep Better. Adventure Better.

Love the simplicity. The concept of the poncho mode makes deciding what to pack for quick kit easy. late spring, Summer,early fall are ideal. Only downside for me it's a little heavy. I do use it also as a comforter at home and car camping.

I absolutely love mine, i haven't had it out for the last several months but just took it out to air out and start organizing for a mid September camp. I use it pretty much nonstop except the few hot summer months, even in the 0-20 degree weather i bring it as an o crap extra protection to bump up my other insulation if needed. i was actually thinking of buying another one for my son but hes not quite tall enough yet. in a few more years i will get him his own. really top quality stuff, have worn it as is in the snow, worn under a poncho, and slept in it. thing is just awesome.

So it's been 10 years since I bought my Sierra Stealth. It has held up incredibly well and is every bit as good as when I bought it. Backpacking a lot less these days but while camping within range of the truck, I use it with my Exped Megamat and wrapped in a Pendelton blanket. It's hard to get up in the morning. Freezing temps do not wake me up at all.

Ordered the JRB Sierra Stealth quilt from Mass Drop and purchased the JRB quilt liner later directly from JRB with the Greylock 3. This combo of of the Sierra Stealth and the JRB quilt liner is perfect for 40° in East TN.

I'm a ground sleeper and I switched to a quilt because I sleep on my stomach and I also tend to sleep a bit hot compared to others. The Stealth is perfect for me. It allows me to move freely in my sleep and I can regulate my temp easily throughout the night. In July I went to the Swiss Alps to do some hiking / camping and the weather turned suddenly. The whole week was rainy and the night temps were dropping to 34 degrees. My Stealth and NeoAir worked perfectly together. I was warm and slept through the night with only a thin base layer on underneath. The pack size and weight impressed everyone I met. I've used this quilt several times but wanted to test it in colder conditions before reviewing. I couldn't be happier! The product and the customer service are both top notch! You can't go wrong with JRB!

As good as it gets. The quality of the Stealth I received was flawless down to the last stitch. The customer service from these folks is the best I've encountered. I've used my custom quilt (active dri down with 2 oz overstuff) on several occasions now and find it suitable for early spring outings where temps can still dip south of 32 degrees. For summer ultralight backpacking, this is nearly a must have item. The compactness, weight to warmth ratio, durability and functionality when used as an overcoat are truly exceptional. I will happily buy from these folks in the future.

Will work down to at least 32F if needed. Great quilt with some good emergency reserves. Bought the longer length with dry down and an extra ounce of fill. Sleeping on the ground on a closed cell foam pad only, I used wool long johns, a hooded light weight down jacket, Jack's own brand down sleeves for my lower legs and wool socks. Except for the sleeves, this is stuff you might have on any trip from late fall to spring. I slept like a baby. Those down sleeve are just great on the legs..

Perfect for UL backpacking; very versatile. I've used mine in the Coastal Mountains in BC at Mt Garibaldi in upper 40F clear sleeping weather- very nice and comfy wearing nothing but my drawers, plus the lightweight was a big plus due to the elevation gains! Also used in Smoky Mountains, one night on Mt Sterling in 20F flash freezing winds - very nice, but needed to wear warm layers once temps dropped below mid 30's. Performed well despite rain and fog before the freeze. Definitely looking to buy more for my sons, and probably add some high sierras for winter hiking. Everyone loves the poncho conversion! When not backpacking, mine keeps guests warm on our porch during winter! Holding up very well with no wear so far.

GREAT QUILT AND GREAT CUSTOMER SERVICE.. I ordered a Stealth for spring and summer trips (regular size with 800 activdry). I got this to lighten up my load and it is very light at 17.5oz. actual packed weight in supplied compression sack is 19oz. and it packs down pretty small at about 7"x8". After taking it out of the box I gave it a little "lofty toss" in the air and it had a just a tad of "hang time" if that makes any sense just to give you an idea of how light it is. The black material on the Stealth has a bit of a "sheen" to it that I couldn't tell from the online pic. They also ship it with cleaning instructions and breathable bag. I like the extra couple of inches it has on the shoulders (52") I'm 5'7" 160lbs. and it covers me well with room to spare. The quality is great, you can sort of tell it's not some mass produced factory item. I tested it twice so far where both nights got into the low 50's (54* and 52*) I slept on the ground in a wild oasis tarp with a Therm-a-Rest NeoAir Xlite. The quilt did great, I slept in shorts and a t-shirt and I wasn't cold nor did I over heat. This is my first quilt and the footbox is a beautiful thing, the ease of getting in and out is a beautiful thing compared to my sleeping bag. The tarp had a bit of condensation but the quilt never hit the sides (that I know of) and the Stealth was completely dry. The quality is right and the price is right compared to the others I was looking at. I ordered it on a late Friday night and for whatever reason I had some issues and hit the submit button a few times. I wasn't sure if the transaction went through but I emailed them to ask if the transaction went through and I only wanted one quilt not the 3 times I tried to make a transaction go through. I got an email early Saturday morning from Jack and he said that the transaction didn't go through and to give him a call after 11am via his cell phone.. yeah, on a Saturday.. on his cell phone, so I did and he took down my info and order specs while he was relaxing at home on his weekend off. I told him I had no prob calling back on Monday, I didn't want to ruin his weekend but he was great and didn't have a problem with it. That's the kind of customer service these guys give you. I couldn't be happier with my quilt and the customer service has a personal touch. I'll be ordering another quilt for winter excursions from these guys. Thanks Jack and Jack, you guys rock!!

I used this quilt during a two month backing trip on the Appalachian Trail and it was awesome! Everyone I hiked with was jealous of how small it could pack, and I was warm the entire time! I love how much range of motion I have when I use it as opposed to mummy bag. When my cold weather bag wears out I'm going to replace it with a cold weather quilt from these guys.

Ideal for my summer trips in the Sierra and other places. Being a side sleeper I found the need to adjust often during the night but hey, I move a lot when I sleep. So this, with a thermo liner (just in case), and a tarp tent and UL mat keeps my shelter and sleep "system" down to 3lbs and a few ounces. Highly recommend.

When I got tired of using a sleeping bag as a top quilt I ordered a Stealth. Since then I carry a stealth as a top quilt when temps are not expected to drop below the 50s (during one colds snap it hit the low 40s and I was warm with the Stealth as a top quilt and a Nest as an under quilt). In the winter I've teamed my Stealth with Hudson River as my top quilts and MW4 has my under quilt and have been warm enough to sleep in only shorts and a t-shirt when the temp was in the single digits. The head hole is great for wearing it like a poncho while sitting in the hammock making breakfast.
