Best Big Wall Sleeping Bag

Thoughts? I'm aware there is another thread regarding this but it was quite old.

Any lightweight synthetic bag rated for the appropriate temperature along with what level of discomfort you deem acceptable.

The marmot ultra elite offers the best warmth to weight of any synthetic mummy on the market with the only other competition being ultra marathon bags like the omm mountain raid. 

Quilts might be fine if you know you will be on a large ledge/portaledge but they make sitting bivvies much colder. 

Top zips are great but difficult to find, old mountain hardwear used to have them. 

I don’t think it matters much. Choose the right temperature for the season and make sure it’s synthetic (not down) if you’re going up for more than one night. Or risk it if you think the weather will be perfect…

I use a zero degree or a 30 degree bag. One is marmot and the other is from the USMC. One has side zip, the other has top zip.

Perhaps I prefer the top zip for the rope to come out of.

Perfect for big walling in patagonia, in the winter. 

Edit: have you ever gone backpacking, wild camped, etc?

Yes many times. There’s 3 options 0,15,32 I’ll probably go with the 15 or 32 but I’m not sure

A 30 degree bag is as warm as I would go unless I was doing something alpine in a shoulder season. 

Does Zion in winter count because I was pretty glad I had my zero degree that night… and we used the rain fly too.

But I was toasty and happy and it’s honestly one of the best nights sleep I can ever remember.

I would consider the 15 degree or the 32. And remember the layers of clothing you bring can really maximize what a 32 can do. So it depends on your clothing and your personal warmth preferences just as much as your route selection and season.

Edit: another real big difference maker is if you decide to bring or leave behind the stove. We often leave it. We may have had it for the night previously mentioned but I honestly can’t recall. 

I’ve been very impressed with my Eddie Bauer igniter.  I want to say it’s 2lb 9 oz or so for the 20 degree long.  

Never big wall climbed, but don't underestimate how much heat you're going to lose from having air below you on a ledge (similar to how hammock campers use under quilts). An insulated sleeping pad will go a long ways (because the insulation underneath you is compressed) to extending (or really, achieving) the temperature rating of a bag. I use a neo air x therm year round for anywhere that I'm mountaineering or backpacking. It's pricey, but worth it IMO.

Big fan of Mountain Hardwear Lamina bags. I have a pair of their warmest ones, rated for -15F or similar. Ten years old, lots of use, still bomber. Always warmth to spare even in the coldest of conditions. I recently bought a 15F Lamina for shoulder season and it's disappointing: marginal if the temps are in the 20s. And it's cut very narrow from hips up; it's a challenge to both wear extra layers of clothing and zip it up the whole way. Ripping the stitching/blowing out the zipper would not be good. The 0ºF Lamina might have been a better option?

Looks like Mountain Hardwear website currently has a limited selection of Lamina bags. Not sure what's up. Supply chain issues? Will MH discontinue the Lamina line? Or are they are planning on coming out with a new Lamina range ???? 

lamina 15 has been bought. As for the whole sleeping pad thing, I have the Thermarest x therm, ultralightweight, and ultra warm.

being a minimalist, I don't carry a bag on walls unless winter/altitude (Alaska, Andes).  A good puffy with hood and long underwear has usually proven sufficient.  for winter/altitude, I've paired the puffy + long johns with a 1lb down bag.  was comfortable at 22000' on south face of Aconcagua in 1990.  call me a dinosaur, but I just hate carrying lotsa STUFF on walls.  been known to sleep in my aiders or use my pack for a hammock rather than f**k around with a porta-ledge.  but suit yourself -- and be warned, I am gettin kinda senile...

My favorite all around utility bag, walling, backpacking car camping.  It is pretty light and packs fairly small for a synthetic bag.

20F Cats meow for most seasons, 0F Lamina or -20F Lamina for winter. And generally the women's version because I sleep cold.
