Why a quilt?

Hey Dan. Users report that the Golite 20 is very optimistically rated… most seem to think it should be rated at 30-35F instead (wearing only baselayers).

Sleeping bags are getting very light these days, and often there is very little weight gain to be had by going with a quilt (perhaps a couple of ounces depending on the manufacturer).

However, most quilt users are quilt users because of their sleeping style… they find quilts much more comfortable because they allow tossing and turning.

I've got a WM ultralite at the moment and have been considering a summerlite or a golite ultra 20 for summer (depending on the region I'm going to). They weigh pretty much the same, but the golite is about half the price of the summerlite… quite a difference. So I'm thinking of giving a quilt a go.

Dan, et al,

JRB ratings assume you are in a protected shelter of some type(Tarp, tent,hammock) out of the wind and in seasonal base layer…Appropriate head gear is required… you should have it with you anyway.

Quilts can be warmer and lighter because they eliminate the bottom of the bag, where the down is compressed underneath you and does very little good. Look at the fill level of a Hudson River quilt (comparable in overall weight to the summerlite). It has 11oz of fill vs 10oz, but in the quilt, it's only on top of you vs being spread thru more area. JRB offers a chart with loft/warmth estimates, and the Hudson River comes in at 20 degrees, so for the same weight, you get a warmer bag than the summerlite, if it works for you.

There's no real reason you'd have to wear a jacket with a quilt any more than with a sleeping. But since quilts are hoodless, you might want at least a fleece beanie. Depending on the weather, you might already be bringing one along anyways.

I think people like quilts because there's more freedom of movement, they're more flexible because it's so easy to vent. It's just like sleeping with your comforter at home.

The main potential drawback with a quilt is the potential for draftiness if you toss and turn a lot.

Good points.
What are the opinions on the JRB quilts? Sewn in foot box or no sewn in foot box?

Here’s two other things to read: The Unconventional Sleep Systems Manifesto and the Review of Unconventional Sleep Systems.”

I have and use both down bags and quilts. IMHO, A down mummy bag with the same amount of fill will keep you warmer than a quilt. Why, pretty simple really, a mummy bag will seal in more body heat.

I have a WM Megalite that I've slept into the mid-20's, with no additional clothing.
I mostly use quilts now, because of me being a side/stomach sleeper, and a tosser/turner as well.

I've used a down quilt rated to 32 deg, where I needed to wear a Capiline 3 top, bottom,socks and a Montbell Thermawrap parka, at, near, and slightly below the rated temp. of 32deg.

Note: that this was with the pad straps around my air matress and not around my body, which seals off more body heat, and is how the quilts are probably rated.

But, with the staps around the body, then you're limiting the quilt in regards to staying stationary and not moving with you, which is the best feature for me, this and the lower weight.

Dan,

Here are a few of my thoughts on bag vs. quilt:

A quilt can be lighter. To compare apples to apples, take the lightest bag, remove the zipper and a few inches of material and fill from both sides of the zipper and you have a quilt and footbox lighter than the original bag with theoretically equal insulating loft around you. A balaclava or down hoody (which you might have in your gear anyway) replaces the bag hood.

A quilt can be more versatile. It can be usable over a wider range of temperatures (hot and cold) compared to a bag. Because it has variable girth, it can be worn over insulated clothing with less restriction and compression. Many can be used as overbags for winter conditions. I warmer weather, a quilt can be used like a blanket more easily than many bags.

Drafts are a disadvantage for quilts, but inside a tent drafts aren’t as much of an issue.

Under the stars, a quilt/bivy combination provides protection from drafts, dew and bugs. Under a tarp, add protection from mist, rain splash and snow drift to the list. I have childhood memories of alternately sweating inside a bag and being eaten alive by mosquitos outside the bag. In hot, buggy weather you can sleep on top of your quilt inside your bivy.

To provide the same versatility and protection in a bag you would also have to use a bivy with the bag. The weight advantage goes to the quilt/bivy.

I still enjoy the cozy comfort of a bag, so depending on conditions I switch back a forth between a bag and a quilt.

Thanks for listening!

Comfort and warmth.
Comfort. I'm a side sleeper who likes to sprawl, and mummy bags are too restrictive for me. I never use the hood either, because i always seem to end up with a face full of down bag.
Warmth. I have a Nunatak Arc Specialist quilt and a Rab Quantum 250 bag. They both have a similar amount of down (the Rab bag has slightly more) but i find the Specialist much warmer. Why? All the down is above me and insulating me. In a bag, the down i'm lying on is being compressed (and thus offering little insulation) or wasted in the hood i'm not using.
