WM Summerlite sleeping bag. Lighter more compact than my older 15° bag.
I've got a WM Sumerlite @32F, which has been rock solid for me in low 30's. I still use it as a top quilt for most of the 30-50F hikes in my hammock. I suspect the Versalite is a solid bag based on the performance of the lighter weight version.
A couple of notes on Western 1) their temp ratings are the comfort ratings, not lower limit. 2) the Ultralite is narrower than the Alpinlite, but if you look at comps the Ultralite can generally be considered a standard width. 3) if Megalite is of interest the Sunmerite is the narrower (again standard by industry norms) version.
I am a cold sleeper too. And I’m embarrassed to admit, I could afford a western mountaineering bag. It was 0°. And I’m 59 and I got the 6 foot six version. Giving me tons of down to snuggle into. I actually use this bag way more than just the winter and I’m always toasty warm.
Western mountaineering. I get cold easily even in the summer in Colorado at high altitudes. I also snow camp
Don’t forget to get a really big bag one that goes way over your head. It’s just so cozy.
I liked my quilt when I was doing shorter trips. Once I started doing months at a time I grabbed a western mountaineering bag and I have no regrets. Helps me extend a bit more into shoulder season
Western Mountaineering mummy bag. I do a lot in shoulder season and these are very warm for the weight
Western Mountaineering, Feathered Friends or Marmot for bags. Enlightened Equipment, Hammock Gear or Katabatic for backpacking quilts. Not cheap but quality and comfortable.
There isn’t really an absolute best, but I like Katabatic for a quilt and western mountaineering or feathered friends for a bag. I prefer quilts down to around the low 20s, bags below that. Having a pocket in your quilt for a sleeping pad seems silly to me.
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… cry once, but once
WM bags are expensive and absolutely worth it. I'll never buy anything else!
