Massdrop needs to start QC of their technical stats. This is not the first time the laws of thermodynamics have been violated in a description.

How is this rated to the temps listed? I just compared this to a zpacks bag and it has nearly half the fill of lower quality fill at the same temp rating? Also it seems to be longer than the extra long zpack options with zerogram stating a 190cm length? Maybe we can have some better specifications?

Massdrop should pull this item. There is no way 8pz of fill will be good to 20degrees. Not a chance.

Yes I agree it seems like a crappy prospect - perhaps worth buying if you want to boost it with a down jacket but then there are cheaper bags with the same warmth....

There is no way this is actually EN tested. Those values are way too optimistic.

Also EN ratings are for sleeping bags, not quilts. So they'd need to supply some sort of hood for the test and mention that in the description here (Enlightened Equipment did that once for one of their quilts). I think you're right, I'm calling foul!

Sleeping bag temp ratings (in marketing material like here) is an area that should be scrutinized way more as it could potentially be life threatening if incorrect. I wish someone from mass drop would chime in.

This bag is way too light to be rated to 20 degrees. I’d be careful about this one.

8 oz. of 850 fill and you say it's good to 20F? I'm skeptical. I have 13 oz. of 950 fill in my 20F rated bag.

I have been kinda waiting for a Zpack bag to come up but this one is intriguing. There are a grand total of zero English reviews I can find though. Would definitely be taking a bit of a flyer on this one.

Anyone with experience with this bag? I’m especially interested in how it compares to the zpacks 20 degree bag.

Agree. And at 40F its not worth $250. I actually really like this design with the foot box and centered zipper, but not $250 for 40F.

Agreed. I really like this design... but obviously skeptical for the reasons everyone else is noting.
