Better sleep layer in quilt

When I roll around in my quilt I can get some drafts, so would go with the jacket since my arms would be better protected at the edge of the quilt.

4 oz beats 2 oz anyday … id just use the vest as a blanket under the quilt

from my experience I would try pulling your arms into the vest, seems to work quite well. Or you could un-zip the vest and drape it over you, again, keeping your arms under it.

I'll take a stab… my vote is for the Montbell UL down inner over the RAB equivalent down vest. I think what seals the deal for me is the ability to better thwart any drafts that make their way under the quilt or through the mesh window of a bivy. I've slept in my Montbell Down T-shirt and had chilled arms under a quilt, but have never had any draft issues or cold limbs/torso while sleeping in my Montbell UL Down Inner Parka. The elasticized cuffs and full coverage in the MB UL Down Inner for my upper body has always kept the cold at bay for chilly nights under desert stars.

Isn't 3-4oz. for a vest quite a bit of down? The Montbell Alpine Down jkt has 4oz. alone. I suppose the vest would be similar to the uber puffy Nunatak Skaha which has somewhere around 4oz. That vest has to be toasty.

Thank you for the replies and suggestions!

I was thinking that the arms might make the difference with regards to drafts, though I am a sound back sleeper.

I already have a MB Down Inner Jacket, but was wondering if using a vest with more down for the same weight would keep me warmer when I am nearing that point when it is getting too cool to use the 12 ounce quilt. I should probably just make a warmer quilt for the same price as a new vest…

if you already have it, then just stick with it …

one trick if yr a back sleeper is to put the jacket/vest on backwards …, or use it as a blanket insider the bag … that way yr not wasting crushed down on the underside … course you need sufficient ground insulation for this …

and youll look like one of those 90s hommies wearing backwards gansta clothes =P

Good call Eric, gonna try that! …though I might not wear it into town, Kris Kross style ;)

Kriss Kross and Cross Colours….. boyyyyyyyyy!

Under a quilt, a down jacket plus a down vest vs. a thicker down jacket with the same weight (thinner jacket and vest combined).
