Unbelievably warm for the weight

i was quite impressed with how warm this quilt is.

Adam Hunt
Solo Quilt 10°F/ -12°C

I'm a tall guy (6'4" 1.94 m) so finding a sleep system is always a challenge. Based on Huzefa's recommendation I purchased the large Solo Quilt. I was surprised how roomy the Solo Quilt was and I could easily snuggle down inside for added warmth.

I tried the Solo Quilt in the open in temperatures ranging from 24°F (-4°C) up to 34°F (1°C) in conditions ranging from a light snow without much wind to breezy conditions with a light rain and I was astonished how effective the Solo Quilt was in maintaining my temperature.

Granted, I conducted my tests in a fairly sheltered area so if you were in damp or rainy conditions you’re going to need a waterproof bivy, tarp or tent so moisture won’t soak through.

Quilts need a good sleep pad system in order to get the best out of it and it took me a while to find a sleeping pad system that was low weight, comfortable and warm.

Eventually I settled on a combination of an air mattress with an R value of 4 and a 1/8” (3.175 mm) foam pad with an R value of .5.

Everyone is different, but this combination seems to work for me.

Like the sleep pad, it took me a while to find some low-weight, insulative clothing that would work in colder temperatures.

Fortunately, Blue Bolt’s sponsored athlete, Peter Van Geit, made some clothing recommendation videos and I modified his recommendations for my needs and I supplemented his clothing recommendations with insulted gloves, leggings, and combining an ultra lite down puff jacket with a light wool mid-layer and a light weight rain shell.

Things I liked;

• The large 10°F/ -12°C Solo Quilt is remarkably light for it’s temperature rating and compares favorably to some down sleeping bags that have a similar temperature rating.

• The quilt’s material feels luxurious against the skin.

• Even if I synch the pad straps close together I don’t feel claustrophobic.

• Dries quickly if damp.

• The “hood” is so fluffy you can almost use it as a pillow.

Things I didn’t like;

• When I received the Solo Quilt it had a funky smell to it but that went away with use.

• The pad strap system is a bit of a wrestling match and I wonder about the longevity of the plastic toggles or if I can get some replacement slotted elastic if I lose or break the strap.

• The toggle system does work well once it’s set up correctly but it’s a bit of a nightmare to manipulate in low light conditions.

• I painted the neck strap snaps with silver paint so I could find them easier in low light conditions.

• Even in an semi-open environment, the quilt does a respectable job of sheltering you from steady breezes but it may not be enough to keep you comfortable once it really starts to blow.

• The Solo Quilt doesn’t compress the way a down sleep system will and the included compression bag is only so effective.


• Use lighter colored webbing for the neck strap so it’s easier to find in low light conditions.

• Pad strap system redesign or, include easy to replacement strap toggles and slotted elastic pad strap in lieu of a compression sack.

• Bypass the compression bag and store your clothing in the toe box of the quilt while hiking so you can minimize how much room your soft goods take up inside your pack.

• Pre-test your sleepwear and sleep pad selection prior to using them in extreme conditions.


Overall, I highly recommend the Blue Bolt Solo Quilt. For it’s comfort, weight and price it’s extremely tough to beat.

With some minor improvements the Solo Quilt could become a much coveted piece of gear for ultra lite Alpine-style hikers or anyone looking to try a quilt without the high cost of entry.

Little overpriced for the quality we get in this range.

This is absolutely a must for who need a good sleeping bank to trek in the mountains at the low temperature

Solo Quilt v4.0


What is a quilt? What is the difference of between that and a sleeping bag?

A quilt is a sleeping bag without the insulation on the back. The idea is – by taking away this least effective section of a traditional sleeping bag, you get an efficient, lightweight, comfortable and versatile backpacking “blanket.” Because a quilt doesn’t wrap completely around you, it feels more like the typical blanket you use at home, allowing you to sleep the way that works for you – on your back, on your sides, or on your stomach.

Without a hood like a traditional sleeping bag, how do I keep my head warm with a quilt?

The traditional sleeping bag does its job well if you’re a back sleeper but if you are like a rotisserie when you sleep, you may flip over during the night and end up face down in the hood.

Our Solo Quilt has a hood – extra length which extends past the neck section of typical quilts. And with its simple contoured design, it is easy to wrap the quilt around the body and over the head. It reduces drafts from coming in and allows you to cover your head comfortably whichever way you sleep.

How do you avoid drafts from coming in when using a quilt?

Our Solo Quilt has a strip of non-insulated breathable fabric sewn around its edges. Its purpose is to close off any accidental gaps that will cause the warmth from coming out.

You can tuck the draft stopper under you to create a cozy cocoon of warmth that is free of drafts or you can let it just lay out on the sides for easy ventilation when it gets too warm. The draft stopper and the hood work together to create a cozy cocoon of warmth that is free of drafts.

What is the purpose of the “pad attachment system”? And how do you use it?

The Solo Quilt’s pad attachment system is simple to use. 1.) Slip the two elastic webbing over your sleeping pad – position them where the toggles that are attached to the sides of quilt will be when laid down on the sleeping pad. 2.) Attach the toggles into slots in the elastic webbing

What is the advantage of synthetic insulation over down insulation?

Synthetic insulation is best suited for wet and humid hiking environments. It does not clump when it gets wet and it dries easily compared to down insulation.

The synthetic insulation we are using for the Solo Quilt is Climashield® APEX. This innovative insulation is the lightest weight and most thermally efficient continuous filament insulation on the market today. It provides continuous warmth and comfort in moderate to subzero temperatures and packs small for every adventure.

What is vapor barrier liner or vbl? And why do you use it on the Solo Quilt?

A vapor barrier is any material that has the ability to slow down the migration of water vapor. This technology is used in liners for clothing, sleeping bags, and other outdoor gear – to protect the insulation from both “sensible” and “insensible” sweat. In hiking environments that makes it hard to dry out your insulation, it’s imperative that you keep your insulation dry and protected from moisture. Otherwise, you’ll have a damp and useless insulation.
