The Mont Zero range is the holy grail of ultralight 2/3 season sleeping bags. We have made every ounce count to give you one of the lightest, full-sized sleeping bag range on the market. The Zero SL is filled with 8.1oz. of 1000+ loft RDS goose down and weighs in at only 14.7oz. The Zero SL Down Sleeping Bag is appropriate for temperatures as low as 36°F and accommodates a user up to 6’ 8" (203cm) tall (XL).

The Zero SL Sleeping Bag is perfect for 2 to 3 season ultralight adventures. From bike packing where every ounce 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.
