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.
825 to 850 Loft 95/5 Premium White Down with water resistant DWR Loft treatment
Down is rated by cubic inches per ounce. The higher the number, the greater the volume per ounce and the warmer the down will be.
This product is filled with Premium White Down with a loft rating of between 825 and 850 cubic inches per ounce.
Mont's down is selected for it's high quality, purity and the fact that it is not live plucked.
This Down has had a DWR Loft treatment applied to assist in damp conditions, decrease drying time, increase resistance to bacteria growth, and increase down lifespan.
