Cumulus X-LITE 200 Sleeping Bag First Look Updated

Herein lies the saga of obtaining a Cumulus X-LITE 200 Sleeping Bag. It is a long and tangled tail of international commerce, and the saga will enthrall you with wonder.

Back in days of yore, when scribed my 2025 paddling gear update, I penned that I wasn’t going to buy any new gear this year, but I was on the lookout for a 30°F sleeping bag without a hood. I kept my eyes open for a bag that would meet my criteria, and decided that at 30°F, I’d likely just bring my Sea to Summit 15°F Spark. That meant I was looking for a bag for the summer. I used to have a synthetic Ferrino that I used often during the summer before I switched to a quilt (quilts being a pain to use, I have left them by the wayside). I decided that something in the 40°F range would be plenty.

Sleeping Bag Options

That led to the hole of rabbits of looking for a new bag. I almost sprung for a Western Mountaineering Monolite. It was close to what I wanted, but the short zipper wouldn’t allow me to open it up like a quilt with a footbox on really hot summer nights.

Then I saw that Gossamer Gear was selling a brand called Cumulus. While I had heard of them in the past, I hadn’t bothered to look closely at their offerings because they didn’t have a US warehouse. Having worked as a outdoor gear chain’s corporate buyer, I was hesitant to deal with any company without a US office, but if Gossamer Gear had them then I figured all was okay. I was looking over their sleeping bags and saw the X-LITE 200. It was similar to the Monolite, but it had a longer zipper. I waffled on buying it for a few weeks and then sprung for it.

What Is This Sleeping Bag?

The Cumulus X-LITE 200 Sleeping Bag is a 900 fill power 39°F (comfort) sleeping bag without a hood. Its claimed limit is 32°F. Its claimed weight is 12.34oz. It weighs 12.7oz on my scale. The stuff sack weighs 0.3oz on my scale. The stuff sack is about the size of two bike bottles. Cumulus claims the bag is 57 fl. oz in size.

It’s made from one of the lightest down-proof ripstop fabrics, and has a 2/3rd length YKK zipper (this is what made me choose it over the Western Mountaineering sleeping bag). Its fit is a close mummy shape, which works well for me at 5’10” and 195 pounds. They claim it can be used up to 6’1″, but I’m skeptical about that. I wouldn’t want to be any taller.

The foot box is what they call a shark fin design and fits well. The top and bottom are filled separately to prevent migration between the two location. The construction is H-shaped in the chambers instead of sewn through. It appears that a mesh is used as the interior baffle wall. It can be zipped together with other X-Lite series bags.

It’s designed for “when quick pace matters, regardless of whether you want to do trail running, ultramarathons, bikepacking or sport rock climbing.”

It comes in orange, which I really like.

The Ordering Saga

I debated about including this in the first look and almost didn’t, but had I read this somewhere it would have given me pause about ordering from an international company with no warehouse in the US. As I noted above, that was my hesitancy until I saw Gossamer Gear carrying them.

A month ago, I ordered a Cumulus X-LITE 200 sleeping bag, and I had hoped that it would arrive by the pony in such a time as in which I could use it before now. And that, dear reader, was my mistake. Unfortunately, I received a defective one. It either didn’t have fill added to one of the baffles or one of the baffle walls allowed all the fill to move to another chamber.

I was disappointed, and Cumulus offered to replace the bag once the defective bag was on the way back to them. It took a few days until they issued a return slip with return postage via DHL.

Using DHL in a Remote Community

This is where I ran into problems. DHL doesn’t directly deliver to my town. Anyway, DHL didn’t show up for any of the four scheduled appointments.

I let Cumulus know, and I called DHL again and asked if I could send it to DHL via UPS, because as I told them I knew UPS would come on time. That led the DHL customer service person to tell me they were going to inform the head of the local DHL station (which is a 10 hour round trip away from my place and that’s the closest DHL office. If there had been a drop off location in my town or even nearby, I would have done that). Cumulus let me know that they had reached out to DHL. Finally, DHL showed up. They showed up when I wasn’t there, but I had left he package open and in a bin outside. Even though I wasn’t there, and even though they said I was required to be there, they took it anyway. Thankfully.

Replacement Received

Cumulus sent out the replacement sleeping bag the following week. I got the replacement bag on August 4th, which was almost a month after I originally ordered it. That’s kind of amazing considering it shipped from Poland to the US and had to be replaced. While a little disappointed (mainly in DHL), I had the bag, and could get on with my life. Then a second replacement showed up. I informed Cumulus, and they are going to pay to have it shipped back.

Initial Impressions of the Cumulus X-LITE 200 Sleeping Bag

I had hoped to have a few trips under my belt before writing this, but due to the saga I don’t, and August is always a busy month for my photography workshops, so I won’t likely get this into the field until September in Grand Teton National Park. I’ll be there for at least 12 days. Because it can get below freezing that time of year in the Tetons, I may not take this sleeping bag. I may have missed this year’s window for using it. So, these are my at home impressions. I hope to squeeze in a s24o sometime in August though.

Smell?

First and I noticed this on all three bags that I received. I have a sensitive sense of smell, and the Cumulus Equipment sleeping bags have all had a different — almost gamy — smell to them. My wife and kid both think they smell of animal. I’ve never noticed that in other down sleeping bags that I’ve owned, so this is new to me. I even smelled all my sleeping bags to make sure this isn’t something in my sense of smell that changed post-covid. The first bag was the worst and almost smelled used. I’m going to need to wash the bag before use, and, hopefully, that removes the smell.

We all should probably be washing all our sleeping bags before the first use anyway just like we do with clothing. I usually do.

Loft?

It also shipped in a very small box that’s only a little bigger than the stuff sack. After letting it air out, it doesn’t seem like the down has lofted completely. It’s almost like it stays clumped together. I’ve never seen this on a sleeping bag that was allowed to loft for several days. I broke up the down, but it seems to clump back together after it is put in the storage bag. This can happen if the bag is stored when wet, but I’ve never seen it on a new bag. Usually, if you throw it in the drier with a couple of clean tennis balls, it’ll loft.

I noticed that after washing, this issue went away and what I have seen is some spots without down just because it’s a lighter sleeping bag without a lot of fill in each baffle.

The Fit and More?

The fit is as I expected it to be. I wouldn’t want to be much heavier than I am (195 pounds). The length to me feels about right, but I wouldn’t want to be any taller for this sleeping bag. It feels like the right fit to get the opening to close around my neck.

The shark fin foot box is really comfortable. It’ll be interesting to see how this works in the field.

There’s a small draft tube along the zipper, and while it didn’t snag in the zipper when I was trying this out on the floor at home, because there isn’t a fabric protector along the zipper, it may in the field. I’ll need to be careful of this. I’m not concerned about this because sometimes you sacrifice to gain the biggest weight savings, and I expected this in this style of bag.

After Washing It (Update on 8/12)

I hand washed it, and I dried it per Cumulus’ instructions. After I finished the smell went away, but the down migrated out of several chambers. So, now the bag has empty chambers and overstuffed chambers. The foot box is empty in two chambers on the bottom and overstuffed on the top chamber. Two chambers on the top middle of the bag are empty.

While the smell is gone and loft in other chambers is better, the bag is essentially useless unless this can be fixed.

Holes in the Baffles Causing Down Migration (Update 8/14)

After washing the bag and finding chambers without down, I wanted to investigate the bag myself and see if I could figure out what went wrong. Worst-case scenario was that I would have to eventually open up the bag and move the down around and stitch up any problem areas.

Except that this seems to be a design choice.

After feeling around on the baffle walls on this Cumulus sleeping bag, it appears that there’s a hole on the inside corners opposite of the zipper on every chamber. It feels like the holes run the entire distance of the sleeping bag like you’d expect in a sleeping bag made with stuff gaps. See the photo below that show my finger pushing into the sleeping bag through one of these corner holes. The second photo shows the corner stitching. When I first found the hole, I wondered if the complex stitching in the corner had just been missed. But that doesn’t seem to be the case. It’s seems like these are deliberately sewn this way to make it easier to fill the down into the sleeping bag. Every baffle that I checked has a hole in the corner.

On bags that are sewn like this the down will migrate between every baffle. After use, the down could end up distributed up and down the sleeping bag in strange ways. In my opinion, that’s not ideal, and in my opinion, it’s a poor way to make a sleeping bag. Having dealt with an older Enlightened Equipment quilt that has this issue, I know it is a pain to deal with. I wish manufacturers that use this process would disclose it on their websites.

In an email to me Cumulus wrote, “When it comes to the down migration, it may happen during a wash and especially the spinning or drying in a tumble drying.” So, it is something that they know about and something that you should be aware of when buying their sleeping bags.

On the upside, I will be able to move the down between the chambers, and at least have a functional sleeping bag. I’ll just have to watch out for down migration. That’s frustrating, but at least I now know that it wasn’t a defect. It was designed this way.

Wrap Up

That’s the first look at this sleeping bag. I was able to wash out the most of the smell. Washing also fixed the down lofting issue, but the down migrated out of several compartment. With about an hour or so of work, I was able to get the down to start to fill the chambers it left. It’s hard to judge if I accurately refilled the chambers.

The question is, having gone through the issues would I order it again? No. You’d have to be willing to live with the down migration if you want to get this bag. Maybe that’s worth it for the weight. It isn’t for me.

In the end, I was able to return the bag and received a refund.
