The word "revolutionary" is thrown around fairly liberally these days, and there arent a lot of products that really live up to that description.  With the Zero Series, Mont has been able to give some meaning to the word.  These bags use a shell fabric that is made up of 7 denier threads woven at over 520 per square inch.  This is probably the lightest downproof fabric available currently.  Combined with 825 - 850 loft DWR treated premium white down, these bags are seriously light, and can compress down to a package the size of your trusty Nalgene.

How is this feather-weight and tiny size achieved?

The World's lightest downproof Nylon
The Zero UL Sleeping Bag uses the World's lightest downproof Nylon: Anti-Gravity Nylon. Superfine threads of only 7 denier are woven at over 520 threads per square inch producing an incredibly light, super smooth downproof fabric: Anti-Gravity Nylon weighs approximately 21grams per square metre!

Anti-Gravity Nylon is extremely light but also sufficiently durable thanks to its super-high thread count, mini-ripstop weave & a double cire heat treatment that also increases down-proofness.

The exceptionally low weight of Anti-Gravity Nylon also allows down to loft to its full potential with minimal restriction; meaning more warmth with less down, less weight & less bulk.

High Lofting Premium White Down
Filled with a carefully measured 138g of 825-850 loft 95/5 Premium White Down the Zero UL provides sufficient warmth for 2 season camping in temperatures as low as 7°C for warm sleepers. Mont's down is selected for it's high quality, purity and the fact that it is not live plucked.

3D Boxfoot for minimum weight & maximum warmth efficiency
The boxfoot provides significantly lower weight & more efficient warmth because of 1) the lack of a zipper and 2) the down chambers underneath the soles of your feet when you're lying on your back.

Ultralight 1/4 Side Zip
A #3 gauge ultralight YKK zip weighing only 4g allows you to climb in and out with ease while minimising both the packed weight and volume.
