Our thoughts:
Over the last couple of years I have steadily switched from a quilt, normally my old Enlightened equipment Revelation quilt. Which I do thoroughly enjoy using, to the Sierra designs cloud 800. For anyone who has read my book, will know that I love using quilts for many reasons – more warmth to weight, no worries about getting tangled in during the night and so on. With that said, quilts do have some disadvantages, which is why I have moved on from them in anything other than summer hikes and hammock camping. For one, I usually find them to be a hassle to fasten onto my sleeping pads.. Usually straps, or buckles or some other headache inducing nightmare at 3 in the morning when I have to get up and pee.
The Sierra designs Cloud 800 has all the advantages of a quilt and sleeping bag without any of the disadvantages. Of course, with some of it’s own disadvantages, but I will tackle that later.
What is the Cloud 800:
Imagine a quilt and a sleeping bag in one. The comfort of a quilt, the warmth and ease of use of a sleeping bag. You fasten your sleeping bag into the sleeve of the Cloud 800 and viola, your done. Your bag won’t tangle you up during the night, and as there are no zippers it’s easy to get in and out. The cut of the sleeping bag is nice and wide, so comfort really is the focus of the Cloud 800 series.
Build:
The Sierra designs cloud 800 is well built using 15d ripstop nylon on outer and inner shell and filled with ethically sourced hydrophobic down 800 on the inside. It’s not the lightest materials on the market, but certainly offers an excellent weight and quality to cost ratio.
Weight:
On the Cloud 800 35 degree bag, the regular weighs in at 660 grams while the large/wide comes in at 710 grams. On the Cloud 800 20 degree bag the weight for the regular is 880 grams and large at 940 grams. Certainly on the lighter end of the spectrum for the two temperature ranges.
Warmth and comfort:
I can’t stand the standard way companies market their sleeping bags. Almost every company markets the limit temp instead of the comfort temp and the cloud is no exception. The Cloud 800 3/ +2celcius degree bag I would say is warm (with proper sleeping mat) down to about +2 degrees. Which is unusual, I find the bags to be warmer than the stated comfort temps. This is also something I have heard from a lot of customers that have purchased the bags from us. When we do have complaints about how cold the bags are, they are almost always coupled with a cold sleeping pad.
As for comfort, nothing really compares to the Cloud 800 in this temp range and weight. Sierra design do have the Backcountry bed which is even more comfortable, but also heavier. Sleeping in the Cloud 800 is very much like sleeping at home in a blanket, it’s that comfortable.
Things to know
The cloud 800 is not built for hammocks, and is very difficult to use in a hammock because of the sleeping pad sleeve. The Cloud 800 does not have down where the sleeping pad meets the Sleeping bag. Like a quilt, SD didn’t see the point in putting down where it won’t work. While this is great when sleeping on a pad, in a hammock it just doesn’t work as you won’t have warmth where you need it.
Also, the design of the Cloud 800 is so that the opening comes up to waist height only, so getting in and out means opening the Cloud 800 and climbing in. Similar to a quilt.
Plus
- Excellent comfort. Perhaps most comfortable sleeping bag available
- Good price to weight
- Great build quality and materials
- Hydrophic down is always nice
- Great design
Minus
- Not great for hammocks – or rather, won’t work at all with hammocks
- Some thicker, wider sleeping pads won’t work with it
