Grab your loved ones and head for the outdoors. The OmniCore Designs M-3D 10°F / -12.2℃ Multi-Down Double Wide Hooded Mummy Sleeping Bag takes care the two of you from early spring to late fall. Slip either two sleeping pads or one double-wide pad into the pad sleeve, and you practically have your own bed in the backcountry. It eliminates the need to zip two bags together, so there will be nothing between you and your loves. At just a little over 7 lbs. this bag’s been independently tested to 10°F / -12.2℃ following the European Norm (EN) 13537 Testing Protocol making it one of the best 3-season double-wide sleeping bags around.

The M-3D Double Wide Hooded Mummy Sleeping Bag 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 Box Design. The 3D Box Construction allows you and your love ones to move throughout the night while ensuring the Insulation can keep you warm. Stuffing a 3-dimensional object (humans) into a 2-dimensional structure (most sleeping bags) will cause area's of the insulation to become too compressed, minimizing it's ability to work effectively. By adding 6" sidewalls along the entire bag we've mimic'd the 3D structure that works so well in down clusters, allowing the insulation the necessary room to work it's magic!

The 75 Denier DWR-treated Polyester Ripstop repel water when a rainstorm strikes your love nest. A zipper on each side of the bag makes escape easy for either of you, and the built-in pillow pocket lets you stuff a fleece in there in case one of you forget your pillow.

Multi-Down Insulation Fill:

Why?  Trying to balance the Pro's and Con's of down vs. synthetic fill is the never ending debate of the outdoor world.  While there isn't an exact answer, in short: Typically Down is Warmer but Synthetic performs better in Wet Conditions. 

So we asked ourselves - Why not use both!  By using both we're maximizing the benefits of both materials while aiming to limit their imperfections

How?  The M-3D's outermost top and bottom layers uses StratusLoft to maximize it's performance in wet conditions.  The 650-Fill-Power Down uses it's amazing heat trapping ability in the layer closest to your body.  A win/win!

Why?  A sleeping bag works by trapping air around the sleeper which then is heated by the body's metabolism.  Looking to nature where Duck and Goose Down is ounce for ounce the best insulator, the secret comes down to space.  The 3D structure of the down clusters that allows it the necessary "loft" to trap air.

How? Stuffing a 3-dimensional object (humans) into a 2-dimensional structure (most sleeping bags) will cause area's of the insulation to become too compressed, minimizing it's ability to work effectively.  By adding 6" sidewalls along the entire bag we've mimic'd the 3D structure that works so well in down clusters, allowing the insulation the necessary room to work it's magic!
