CloudLite

If you can swing a WM bag, it’s so worth it.  FYI - I got 20% off of mine from REI last year! Their sale ends on the 24th!

I did, with overfill. I've only slept in it two nights. Low of 35 f so not really testing it. But it was very toasty. So much so I had to sleep with it unzipped. That's on a Nemo Tensor Extreme which I'm still making my mind up about.

I can give you my closest response. But it doesn't exist. And if you have the budget for it here's the closest response. The Western mountaineering Cloudlite, and I'd recommend getting it with overfill. Here's why. It opens up all the way so you can use it as a quilt. It has continuous baffles so you can slide the insulation on the bottom half. And that means it can be versatile up into higher temperatures. But like any bag it's going to have its lower limit. And I'm not talking about the rating. I mean like the actual point where you're miserable. So this one's going to probably keep you warm with the overfill to about 17 f. I would say comfortable there. The company may say that it would keep you warm, with the overfill, down to 10 f. And maybe with a little layering and a sleeping bag liner you might dip down into the single digits depending on whether or not you sleep warm. Any colder than that and you will want a warmer sleeping bag. So be very realistic about what temperatures you're going to be camping in. And if the answer is that it's 20 F and up, there are a plethora of bags that people consider to be three season bags. They can cost half the price of a Western Mountaineering bag. But if you're going to actually do winter camping, then you're going to be so much happier getting at least two sleeping bags. Something like a 20f EN or ISO rated bag, and then a 0 f EN or ISO rated bag. Building 10°. So if you get a 20 F bag, expect to only use it when temperatures are going to be about 30 f. That gives you some leeway. At that point switch to your winter bag. Most importantly, if you think you're going to experience temperatures below zero, you need to get an expedition bag. They exist. You can get -15f, -25f, whatever. Again it's just about being realistic with your expectations. I'd say for now just start with a quality 20f bag that is EN or ISO rated. And then if you're going to do some winter camping buy a bag specifically for that.

Good pad. Stick with that. Edit: (I forgot about the Nemo eclipse. That's something to look at. I don't think they're ready to ship yet. I don't know that factually. I think they're officially going on sale in march. REI was doing pre-orders.) Someone mentioned Western Mountaineering. That's the best. But they're expensive. I don't know if I'd recommend it for a beginner. I have one and it's totally worth it. If you know you're going to be out there, then maybe eventually you want to make that investment. In general about sleeping bags look at the EN or ISO Comfort rating. If they don't have that, you probably don't want it. That's an incorrect statement. Because even some top brands don't necessarily publish that for certain bags. In which case you just really need to look deeper into that bag. To give you a specific example, Western Mountaineering has EN number is published on a chart under their faqs. But that only goes down to their bags that are about zero rated and above. That doesn't mean that they're cold weather bags are crap. The exact opposite actually. But a lot of budget brands are throwing a temperature rating on there that may be more related to the extreme limit number which is survivability and you'll just be cold. If you want to look at the difference between the comfort, limit, and extreme limit rating, you can. But just stick with comfort. Maybe build in an extra 10° from what you actually expect to sleep in. That's a heavy tent. You can save a lot of weight there. Let me offer a specific alternative. Durston Xmid 2. It's a trekking pole tent. If you wanted to try trekking poles, this is a great way to save weight. If you don't want to use trekking poles, Durston sells ZFlicks poles. You'll still be significantly lighter than the Half dome 2. R/durstongearheads Naturehike is a budget brand with tents you can look at to see if one would work for you. You'd save money. And probably can come out a fair amount lighter. Check out r/ultralight. I'm not saying you should go full ultralight. But if you're going to be backpacking, save weight where you can.

Western Mountaineering has sleeping bags that you can order with one being right zip and one being left zip. And then you just zip them together. But I'm going to be honest. I don't know your friends and family. That's not something I would put on a wedding registry. And I don't mean I wouldn't put sleeping bags on there. I wouldn't put Western Mountaineering on there because it's so freaking expensive. I have one. I bought it for myself. I'm okay with that. I'm just saying I wouldn't ask anybody else any kind of obligated way like a wedding registry to spend that much money on me. What I'm seeing from the comments is that there are probably other brands that can do this. I just don't have a more affordable specific recommendation. So a little research might turn up a good result. I know a lot of brands are going to use zippers from similar suppliers. But my sort of guess is that you'll be better off finding a brand where they specifically state their bags zip together and then get two from them that you know are compatible.

you might take a look at this: I can tell you this company is known as "The Mercedes" of sleeping bags and they have something extremely close to what you are looking for. Their temperature ratings are generally regarded as "conservative." I can go into more detail about that if you want. Their ratings are "comfort rated" (not survival rated) and still conservative. You would be going from a rickety Cessna to a G5 Private Jet plane. If you pair this with the right high R-rated bag and layer right (sleepware) I think you'll be great. Bonus they make a 5'6" bag. I've used their bags over 30 years and can't say enough great things about them. [https://www.westernmountaineering.com/product/cloudlite/](https://www.westernmountaineering.com/product/cloudlite/)

Almost forgot- there is an option to add "overfill." You can 1) special order it through the dealer 2) order the bag direct from WM (they ship uber-fast, fyi). The cost of the overfill adds $59. Not sure you really need it but wanted to let you know it exists. I think you will crush your requirements. I know the quilt recommendations are awesome products and the comments about "squishing the fill" aren't inaccurate but ... i've got a feeling you are a VERY strong hiker and a 2lb 3oz (or 2 lb 6oz) bag will not be an issue for you to carry backpacking. I'll go an extra step where I spend a good deal of time each year (in Colorado) you may have a doppelgänger who has blitzed passed me multiple times. You've got this and the company is top-shelf.

I hope it lives up to how much I hyped it. My favorite test of any bag is the "snooze test." Basically you get in and if you immediately tune out everyone and everything around you and basically feel like saying "uhmmm I good- thank you-- can you (to the sales associate if they hover) give me a few minutes to really get a feel for the bag?" (and then start to drift....) it then squarely passes the "snooze test." Hope it works for you! Post how it goes - yay or nay.

You have (totally unfairly) stumbled into a really under-served market niche. Most rectangular sleeping bags are aimed at car campers, and they won't be warm enough or perform well enough for what you need. And most makers of performance sleeping bags and quilts that emphasize weight make mummy styles only. I'm not plus size but I am a side sleeper, and a more generous cut is crucial. Western Mountaineering is one company that comes to mind that makes high-end, performance sleeping bags and also includes some more generously cut styles (semi-rectangular) among its offerings. [Spec page for all their bags](https://www.westernmountaineering.com/about/sleeping-bags-specification-chart/). Maybe something there could work — like the CloudLite? WM bags are really expensive, but they are a big enough company that they have real life stockists, so you can try it out, and you can occasionally find their stuff on discount — I got my WM bag using an REI member 20% coupon during an annual sale.
