“There was a time when I thought hikers that used synthetic hiking gear had no clue what they were really doing. I was so wrong. Everything about what I have learned and experienced using the Mountain Laurel Designs ‘Spirit’ 28 ° Quilt, has just further confirmed to me that the decision I made last year to make the switch was a brilliant decision.” – Thru Hiker & Trail Builder John Alba |

Many users of the Spirit Quilt use it on top of a 2-3 season mummy bag, for full winter temps. Doing so helps keep a down inner bag dry. In below-freezing temps, insensible perspiration from your body or wet clothing cools as it moves through the sleep system. Some of that perspiration condenses back to liquid water near the colder outer surface. Using a synthetic quilt over a down inner bag, holds more of that moisture in the faster drying synthetic layer, so the down bag stays dry and the synthetic quilt dries fast and retains most of it’s insulation when wet. Most hikers switching from a full mummy bag to a quilt get the hang of it after a few nights. Commitment!

The Spirit Quilt 28 °, is a true Ultra Lightweight Specialists tool; if you are new to backcountry sleep quilt systems and their use, please read the entire product description and specs before adding to cart.


• Large foot box for more comfort vs other light weight quilts and bags. Allows the use of insulated socks, booties or other clothing in the foot box with out compression formed cold spots.
• Can be used over ALL other bags to boost temp ratings because the foot and leg circumference can be adjusted – unlike a fixed foot box quilt.
• Hammock Under Quilt Use Ready : Corner webbing loops for use as a hammock under quilt.
• Foot box and lower leg area is larger than many other lightweight quilts. Body mapped shape offers warmer torso area and less bunching at the neck.
• Anchored no-fumble cord locks at each end.
• Removable dual sided adjustable back strap. Back strap has a long webbing to secure under a sleep pad. Sleep pad elastic clip on connection system supplied to make it easy to clip the quilt on and off of a sleep pad if desired.
• Quilt can be reversed to use inside out if one side gets wet.
• Head and Foot elastic cord sleeves.
• Foot box vent plug for the Spirit 28 and 38 – Prevents heat loss through the tiny gap after cinching the foot box closed.
• We recommend Black or Olive Green color, for speed drying

Available in small, medium, large, x-large, and custom sizes. See “Specs” tab for dimensions. Color(s): Black, Olive Green, Citrus Orange (See “Quilt Options” tab for color recommendations.)

SHELL & LINING: MLD Endurance 10D X 10D 3x DWR RipStop 0.74 oz sq/yd
The very best lightweight sleeping bag fabric available. It has a high thread count density for strength. Our 3xDWR shell and lining fabrics are an important part of the thermal equation. The liner and shell are tuned for air permeability to limit condensation and slow heat transfer to boost the the overall warmth rating.

INSULATION: Climashield Apex Synthetic
ClimaShield APEX is the most thermally efficient synthetic quilt insulation available. It drapes, compresses, and recovers extremely well and does not requiring through-stitching baffles to stabilize the insulation- that eliminates compressed sewn areas and prevents cold spots. Many other synthetic insulation’s require sewing of the insulation to the bag shell (you can see the many horizontal seams on the outside and/or inside of the shell) to prevent shifting or tearing. Apex is a modern continuous long staple type of insulation and does not need quilting in this type quilt and retains all of it’s Thermal Clo Value. Some synthetic insulation’s made for small panels in clothing that that test good Clo ratings loose much of that thermal efficiency by quilting to stabilized the fragile insulation matrix. Sewn through insulation generally cannot recover as well to multiple tight compression over time.

COST: Included.

Customize your quilt by choosing the outer and inner color! Color Choices now include: Black, Olive Green and Orange Citrus.

NOTE: We suggest getting Black or Olive Green as the INNER color for faster drying times.


The MLD Spirit Quilt is very similar to the time-tested and well proven FKT Quilt. Both quilts use the same super high quality ClimaShield Apex Insulation and MLD 10D RipStop shell and liner fabric.

The Spirit Quilt has the same insulation thickness all over, and the lower leg area closes with soft Velcro Omni-tape and snaps.The FKT Quilt has 4 oz sq/yd insulation in the lower half of the quilt, and 2 oz sq/yd in the top half. The lower leg area closes with five snaps – no Velcro.

The Spirit Quilt is slightly wider than the FKT Quilt, and while the Spirit Quilt can be purchased in 28, 38, and 48 degree ratings, the FKT Quilt comes in one temperature rating.

  1. John Abela

    I have been using the MLD Spirit 28 since 2014 and it is my go-to quilt for temps that the MLD FKT cannot reach. The Spirit 28 has been around a long time and has been used by some of the most well know big mileage hikers in the world, and for a good reason. Before getting mine I asked around the smallish group of hikers with 10,000+ miles of hiking that use synthetic quilts, and the absolute 100% consensus/recommendation was the MLD Spirit 28. So glad I listened. If you need a quilt for this temp range, just buy this quilt and get it done and over with.

    I have owned the 28 degree Spirit Quilt for several years now. I’m 5’11, 180ish lbs and own a large. The fit is good, and it will cover up to my nose when pulled all the way up. What I like about it: warmth to weight ratio, build quality, versatility in most weather conditions, and fabric does a great job at trapping air and retaining it. Dislikes: I feel the 28 degree rating is way conservative. Maybe its good for a woman, but as a man, its a thermal nuclear reactor underneath. I swear I’m radioactive some nights even when the temp is high 20’s low 30’s. I’m wearing the minimal clothing and MLD Bivy. If your a cold sleeper than maybe its for you, but I would recommend going 38 if you want a quilt that you can use more often in a greater temperature range.

    But! This quilt is a go to. If you’re a gram weenie, and using a low volume pack, then I can see you wanting a goose down sleeping bag, but after my switch, I really don’t see a need to have a down bag. This bag has not lost loft in the East on the A.T were my down bag has, and when I’m hiking in the West where its dry…mostly, I still can get to a 7lbs base weight in 3 season hiking conditions.

    Recommendations: I would go with buttons instead of Velcro as a closure system. It will help lighten it up a gram or two, and stop your socks getting stuck to the Velcro. 28 is in my opinion much warmer. 15-20 is my comfort range. Go with a 38 if youre thru hiking the CDT or PCT and, A.T if you are SOBO.

    If I were single I would probably use this as my everyday quilt! I used this for 3 nights on the southern AT. Nights were in the mid to upper 40s and I was plenty warm in my large tent on a decent inflatable insulated pad. Footbox was closed but the rest of the quilt was open. Using a single wall tent, I had some condensation that did get on the quilt with no effect on the warmth. I have an XL and while compression is not comparable to down, it is still fairly good with the right compression bag and the weight is good. I’m very pleased with the product and would highly recommend.

    Used my Spirit 28 Quilt last weekend in 26 degrees and high winds on top of a thermorest pro life pad. I was plenty warm enough in socks, long johns, ls top and light fleece jacket. I like the footbox zipper. The pad strap kept the quilt in place. Also liked being able to snap it together behind my neck. That really increases the warmth. It performed as I had hoped it would. I got a large and it fit my 5′ 11″ 195 lbs fine.

  5. Jeff Borne (verified owner)

    Took my Spirit 28 out for it first trip this last weekend on the Oregon Desert – Badlands Challenge
    Spent 2 nights out in the Oregon Badlands Wilderness
    1st night – light drizzle and temps in the high 30’s to low 40’s
    2nd night – cloudy after lots of rain and temps in the low 30’s
    Quilt performed AMAZINGLY! Stayed warm and cozy both nights.
    I have been using a Feathered Friends Flicker for years, but I think I may have a new favorite go to
    Thanks again MLD for creating amazing gear !

    Spent two warm nights in a camp that was cold in all seasons, (-2 degrees c)
    Many small designs are good, worth buying

  7. Peter (verified owner)

    I used this quilt for my PCT SOBO last year, with night temps ranging from 75-20 deg F. The ability to lay the quilt flat like a blanket was a huge plus in the hot or slightly cool summer nights, while at the same time this quilt also synches up nicely when pushing the lower limit.

    Having a synthetic quilt is a huge plus; I cowboy camped most nights and sometimes woke up with condensation when I didn’t choose my campsite wisely. That never effected the warmth of the quilt, and it dried quickly when splayed out the next day. I would definitely recommend this quilt if you’re looking for a versatile piece of gear that will work great in most 3 season conditions.

    I’m 6’1 175 lbs and use the XL which fits great lengthwise and has a roomy width.

    Just back from a backpack in highlands of Scotland. I am a cold sleeper and so this was ideal for a cool spring night or two. Used it in a sinylon single skin tent with plenty of condensation, which was not a problem with this quilt. This is also my quilt of choice for an afternoon’s nap 😉
    The footbox system is pure genius and the warmth to weight is awesome. The only issue is the air trapping outer takes a bit to squash into a stuffsack but nothing serious. I have used many many sleep systems including best quality (1000) down, synthetic and pile (Buffalo) I wish that I had started with this quilt. Tempted by a 38 to get the poncho slit.
