Sleep warm all night long with the OmniCore Designs Ultra-Lightweight Multi- Down Mummy Sleeping Bag. We’ve tried to cram as much features and benefits into the smallest and lightest form factor. At around 3-5lbs. these bag’s have been independently tested to -10°F / -23.3℃ to 30°F / 0℃ following the European Norm (EN) 13537 Testing Protocol.

The M-3D Ultra-Lightweight Mummy is powered by our innovative Multi-Down technology. We’ve used Stratusloft in the outermost top and bottom layers to maximize warmth insulating performance in wet conditions. In the layer closest to your body, we’ve utilized the amazing heat trapping ability of the all-natural 650-Fill-Power Down. Another key feature designed just for you is 3-D Footbox allows back sleepers a more natural and comfortable night’s sleep by reducing the tension on your feet while in the bag. We’ve tried our best to optimize the “right” mix of down vs. Stratusloft to maximize performance to weight ratio!

The OmniCore Designs M-3D Ultra-Lightweight Multi-Down Mummy Sleeping bag comes in two sizes. The regular size is fit’s most body types of people up to 6’2”. For taller individuals we have the XL will fit most body types of people up to 6’8”.

The shell is made of an ultra durable 75 Denier DWR-Treated Diamond Polyester Ripstop which when combined with our Stratusloft outer fill, will keep you dry longer when wet conditions hit!

NOTE on EN 13537 testing: The testing standards were created to help provide an apples to apples comparison between various bags. The test uses heated mannequins wearing long underwear and a hat and assumed that the bags are used on a sleeping pad. Also, these mannequins do not move during the test which minimizes the amount of heat loss that occurs during a normal person sleeping for 8 hours. Because of these variables, we recommend choosing adding 20-30F to each bag’s rating to maximize comfort.
