0 degree bags that are STILL COMPACT

[Jens22]

western mountaineering down 5 F with a twin flat sheet (cotton) and you'll be happy with both. That bumps up the warmth and compliments the smallest footprint for stuffed and packed system.

Thanks!!

Another vote for Western Mountaineering, I have an Antelope MF. Great bag.

Thank you!

 

[Jens22]

Seconded! This is a great cold weather bag. The reinforced foot box is great and the neck collars seal out a lot of draft. I have packed this bag many times.

Thanks!!!

Nemo sonic 0 compresses to the same size as my big Agnes 30 bag (synthetic). Seems small to me.

Thank you!!

I second the stone glacier zero degree. Packs down small, very roomy inside and warm.

Anyone have any experience with Taiga sleeping bags?

A lot of manufacturers 0 deg bags are actually more likely 20 deg bags. If you want a true 0 deg comfort level bag then expect to have more down fill and a bit more bulk and weight. The higher the fill power, the lighter the bag you'll get. Western Mountaineering and Feathered Friends are the best there is. Stone Glacier also has a following. I personally use Feathered Friends, but if I was buying a new 0 deg it would be the WM Kodiak.
If you are looking at the backpacker brands like TNF, Nemo, Mountain Hardwear, Marmot, Big Agnes, etc. you should be looking at their fill power and fill weights and comparing them to WM or FF. Check for their comfort ratings vs their advertised lower limit ratings.

My wife has one. She loves it and it seems really well made. I need a new bag and would buy one if I wanted a mummy bag but I'd like to try a quilt and they don't have a 0 degree. If they had a 0 degree quilt I wouldn't look anywhere else. Partly due to the quality and partly because they are made in Canada not too far from me.

I will add that I love my 0 degree EE quilt but I would not call it a 0 degree sleeping component. With a thermarest xtherm the quilt reaches its limits at 20 for me.

this could be a simple solution- 60 degrees on it's own, adds 5-ish degrees to your existing bag

all of 3 oz

so this is a 60 degree but adds 5 to bag? I got all excited about a 60 degree liner

You can currently get the Marmot Never Summer 0* for $600 less than the WM Kodiak and it's only 7oz heavier, fits into the exact same size stuff sack, and has the exact same comfort rating. For $150 on sale I don't know that there is a better deal out there.

Comparing 6ft WM Kodiak at 30oz of 850+ plus fill to 6ft Never Summer at 31.5oz of 650 fill you can see it isn't apples to apples. 30x850=25,500 vs 31.5x650=20,475. The Never Summer uses lower quality down and a more aggressive bag taper. Never Summer is a good bag, but it isn't nearly to the level of the WM, and is priced accordingly.

I can guarantee you that 31.5 oz of 600 fill does not equal the temperature rating of 30 oz of 850+ fill- no way, no how.

 

[BDRam16]

Well it’s hard to tell what WM actual rating is. According to their website, it’s “somewhere between comfort and limit.” So if it’s rated at 0* and that’s between comfort and limit assume the comfort is maybe 5ish*? The comfort on the Marmot is 9* and I’ve had it lower than that and been plenty toasty, but I am a warm sleeper and I like the tight cut. I’m not implying they are the same, but for a $600 difference, based on my real world use of the Marmot, I would recommend it not to be over looked.

 

[mtwarden]

It's definitely a good buy, no argument.

I find WM (and FF) to be pretty conservative in their ratings; pretty safe to assume a 0 rated bag is going to be comfortable at 0.

30 oz of 850 fill yields ~ 25,500 cubic inches; it would take ~39 oz of 650 fill to have an equivalent loft.

In addition to less weight for equivalent warmth, higher rated fill also compresses better than lower rated fill (ie less volume)

Is that worth that much more $, that's for the end user to decide

Comfort — the temperature at which a standard female can expect to sleep comfortably in a relaxed position. Lower Limit — the temperature at which a standard male can sleep for eight hours in a curled position without waking.

This is what the EN rating means.

Those ratings are averages, if the individual is a warm or cold sleeper they need to take that into account when comparing bags from different manufacturers, or even bags from the same manufacturer.
