“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 38 °, 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

The optional poncho head slot adds more versatility, allowing the quilt to be worn around camp, as an emergency torso layer, or as the only insulation layer in warmer conditions.


We hesitate to offer exact temperature comfort ranges, as there are so many variables. The following temperature ranges assume users understand standard UL clothing, shelter, campsite selection, and UL quilt sleeping strategies. With multiple years of testing and extensive customer feedback from many many users – we feel these ratings are a good general guide to your comfort level.

NIGHT TEMPS OF 38 F | 3 C: Long sleeve shirt, long pants, socks, light balaclava
NIGHT TEMPS OF 32 F | 0 C: Lightly insulated clothes, 4.0 oz MLD APEX Balaclava, bivy or enclosed shelter
NIGHT TEMPS OF 25 F | -4 C: More insulated clothes, mo-better balaclava, real nice socks, and the SuperLight Bivy or enclosed shelter

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.

WHAT IT IS: A 12″ horizontal slot added in the middle of the quilt, that closes with three low-profile nylon snaps.

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.

    Wow! was my first impression. It is everything I expected. I gave 4 stars since nothing is really ever perfect but this is darn close. Thank you. Shipping from VA to CA was quick. This quilt will make an excellent addition to my layered sleep system for the multiple environments we have here in NorCal. As of this writing, I was all set to go to the local campground for a few days, my norm for gear shakedown, but it cancelled today because of the C virus. Whelp. Looks like I’m sleeping on the back porch. Being that the insulation is Climashield APEX, my understanding is that it can stay compressed almost indefinitely. That can be helpful although I still tend to hang things in my closet. Thank you again for a great product.

    Yeah, this thing is pretty great. I’m not gonna lie, I’ve cycled through a LOT of UL bags and quilts trying to perfect my kit. That said, no matter how many times I’ve been tempted to try something new, I just can’t quit this quilt. It just works so damn well. It is easy, small, light, no fuss, resilient and warm. It’s everything I need in a quilt. It’s light and breezy enough for summer duty, but it’s also easy to push the comfort limit down to freezing by throwing on the hat and jacket you’ve packed. Have been extremely happy with this quilt and enjoy it everytime I reach for it. You will too.
