The Mont Zero range is the holy grail of ultra light 2/3 season sleeping bags. We have made every gram count to give you the lightest, full-sized sleeping bag range on the market. The Zero SL is filled with 275g of 1000+ loft RDS goodse down and weighs in at only 417g.

The Zero SL Down Sleeping Bag is appropriate for temperatures as low as 2°C and accommodates a user up to 203cm tall (XL). The Zero SL Sleeping Bag is perfect for 2 to 3 season ultralight adventures. From bike packing where every gram counts, to ultralight multi-day walks. And because of its tiny packed size and super light nature the Zero SL can be used as an extender to your existing sleeping bag, or as a just-in-case for backpacking odysseys.

Anti-Gravity Nylon is an ultralight fabric that enhances the performance and reduces the bulk and weight of down sleeping bags. The exceptionally low weight of Anti-Gravity Nylon allows down to loft to its full potential without restriction; meaning more warmth with less down, less weight, less bulk.
