0 degree sleeping bag

[high country]

If you are not backpacking with it, don't mess around-buy the -35 oversize bags. Spent a couple of nights hunting in Utah where it was so cold our Igloo water jug froze solid and all beer and pop cans exploded, still slept warm.  Much easier to un zip and throw off a bag that's to warm than to try to stay warm in an under rated bag.  Unless you have to for back packing, I would never consider a mummy bag unless you have a body that resemble a pipe cleaner. Oversize is the only way to go!!! (They're cheap enough these days a person can own 2 easy enough-one for summer and one for winter)

When i got my ultimate thule by wiggy's I tried it in the yard on a pad without any cover. It was just below zero and i woke to a frozen shell, but was cozy warm. That is a seriously warm bag.

when I see the degrees posted on bags,Like, good to 15 degrees,Im sure that means you wont die at 15 degrees,but your gonna freeze your ass off all night...I had a zero degree mummy,stayed warm at 12 degrees but was most uncomfortable in it..to tight

Most main stream manufacturers are now using the EN rating system which does help standardize and provide a more true rating for the bag. A +15 bag from many of the major players is really going to provide you true +15 warmth now for most people. This does take into effect that you are wearing midweight long underwear, socks, a hat, and are using a sleeping pad.

Golite is having some sales if you care to research them.  I have a golite 20* down bag and I'd take it a bit below 20 myself...  I believe their 0 bag comes in right around 3lbs.

I say go with the Big Agnes sleep system. There are many advantages to having the sleeping pad incorporated within the sleeping bag. You can't go wrong especially if you ever sleep in a bivy or Hannessy Hammock.

Feathered Friends bags are top notch.

That is true.  My father has a BA and that is a nice little set up (with the pad inside the bag).   The only downfall I can see is, when using a floorless shelter (like mine) his sleeping bag was literally on the ground/dirt.   I used my pad as the layer between my bag and the dirt.   The only way to get around this is to carry a ground sheet (more weight).

I vary pads for conditions. I WAS really happy with my REM pad till it developed a leak that I could not find.....but if it is going to be cold (20* or less) the air pads don't keep me warm. At that point I go for a classic ridgerest.

They are awesome for everything shy of backpacking. Well built, huge zippers and warm....but compressability is about equal to steel. Make sure if you buy one, you don't give jerry your email addy.....he is herpes to the spam account, he just won't go away.

At 3pounds 8ounces, I've liked my Northface Snowshoe with good a sleep pad down below zero, but I am not broad shouldered. A big guy would have trouble in this model.

I guess my pack is bigger . but typically I only carry the inside bag while back packing , never been cold in it .

If you are cocerned about weight you might think twice about Wiggy like High Country said. I have used mine on float hunts where weight is not as big of an issue. Plus mine is synthetic and don't compress as well as a dwn bag in a compression sack.

My badger is roomy and dang warm too.....and I could carry at least 3 in the space my wiggy's takes up.

I have a REI sub kilo 20 bag and I haven't been cold in it yet.  Temps down to the teens only.  I wear a wool beanie and wool socks which might make it warmer than I think.
