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 825-850 loft down and weighs in at only 437g. The Zero SL Down Sleeping Bag is appropriate for temperatures as low as 2°C and accommodates a user up to 6 feet tall.

The Zero SL Sleeping Bag is perfect for 2 to 3 season ultralight adventures. From trail running overnighters where every gram counts, to multi-day walks along the coast. 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.

Note: Sleeping bags can take 5-10 days to arrive in store, before being shipped.
