Maximise your backpack space & minimise your carried weight with the Zero UL Sleeping Bag. Perfect for spring and summer bike packing, ultralight bush walking in warmer climates or as a liner for your existing sleeping bag.

The Mont Zero UL Sleeping Bag weighs only 300g, packs to a size no more than a 1L bottle and accommodates a user up to 200cm tall (XL).

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 only, 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.
