Which puffy jacket to extend the warmth of my quilt?

Montbell rates them as the same warmth. The Ex Light has slightly less down but higher fill power. It also costs more and has a lighter shell.

Lower fill power could be more resistant to moisture but otherwise it’s a simple comparison of weight vs price.

Hey Paul, thanks for the reply. I couldn’t seem to find the warmth rating on the montbell website. I think I am going to go for the ex Light for the 2.5oz weight savings.

Thanks again

I have the superior parka and the alpine light.. I chose the superior over the anorak just because I like the larger baffles and the fabric felt too fragile on the anorak.  Im also a fan of having a full zip to vent without taking it completely off if needed.

I love my alpine light but had to return the first one after a week due to some stitching coming undone and down leaking out due to what looked like them cutting the fabric too short before sewing (return was hassle-free and they just gave me a new one).  I am having the same issue on the second one that happened about a month later in an area where it is double stitched so no down is leaking but is still annoying to me.

I have an alpine light. Just too good a value and can be used in a wide range especially when stacked over another garment.

For sleeping in I would take a pullover as a matter of course rather than one with a zipper if that was an available option. But for sleeping in I always add a crutch strap to stop the garment from riding up during my nightly thrashing around. Make sure your windproof layer fits over the sleeping layer down just as added insurance

I can’t speak for the Andes but the Colorado Trail in August  will probably have you using a down jacket as a pillow far more than wearing it with a 20* quilt.   For that, you may as well chose the lightest option.  I have the Mont Bell Anorak and use it with my EE quilt as you plan to do, it makes for a great sleep system in cooler weather. I just don’t think you’ll use it that way in August much, if at all.

Thanks for all the great info everybody. I pulled the trigger on the ex Light Anorak… I think it will make a great layer for my sleep system on my trip to Peru, and shoulder season hiking in the States. For $269 it better make a comfy summertime pillow too.
