Trestles 0

Not sure if weight matters, I have an older version of the marmot trestles 0°f/ -18°c synthetic fill. I find it to be a very warm bag. I have been comfortable in that bag sleeping in my jeep on a cold Vermont night. It’s $200 usd not exactly the most packable or lightest bag I own but it’s def warm.

Rab all the way. Check the ratings too. Marmot rates by limit. I'm not sure if rab rates by limit or comfort but In my experience their gear is much warmer and better. Their down is the shit

DO NOT BUY A KIDS’ BAG. They are not rated accurately in comparison to adult bags. I’m 110lbs/5’3” and I brought a kid 0F bag on the John Muir Trail. Learned the hard way.  I have a 0F Marmot that I love.

Marmot “zero” owner here — it’s a safety rating, I am cold AF below 20 degrees in the bag. I trust no one but Big Agnes on ratings because they give both and *use* their own products.

Are you sleeping on your side? I had a sleeping bag, a Marmot trestles that had less fluff on the bottom and when I changed from back to side sleeping I would wake up cold..REI will allow you to exchange the sleeping bag or get a refund if its less than a year old. Also, what height are you? A bag with a lot of space in it, a bag that is for someone 6 feet and you are 5 feet will not keep you as warm because of all the empty space that has to heat up first.

Western Mountaineering, Feathered Friends or Marmot for bags. Enlightened Equipment, Hammock Gear or Katabatic for backpacking quilts. Not cheap but quality and comfortable.

For a lot of backpacking brands, if you buy 2 bags; one with a left zipper and one with a right zipper ; you can simply zip them together (along with using them independently. I have Marmot bags that do this so my wife and I can carry our own gear but sleep together.
