Sleep in a bed, not a bag.
Sure, mummy bags are warm, but they're generally very constrictive, uncomfortable, and downright unnatural. "Hybrid" sleeping bags (bags that integrate the mattress) provide a compromise. The idea is simple: remove the weight that's crushed underneath you in a mummy bag and thus rendered thermally useless and re-allocate that weight to address the mummy bag's inherent constriction and lack of versatility. In theory that's great, but combining a sleeping bag with a mattress tends to create more constriction by pinning you to the mattress. To address this, hybrid bags tend to be much larger, less thermally efficient and—you guessed it—heavier.
We decided it was time for something better. The Zenbivy Bed is the first hybrid sleeping bag of its kind that not only matches a mummy bag in warmth/weight ratio, but does so while eliminating constriction and providing unparalleled versatility, excelling in a much wider range of temperatures.
Solving The Hybrid Dilemma
Traditional hybrid sleeping bags pin you to the mattress and are oversized to try to allow space for natural movement, which ultimately just ends up making them heavy. The Zenbivy Bed easily solves those problems. By attaching the top quilt to the hinged "wings" of the fitted sheet, the Zenbivy Bed is instantly free to get wider where and when you need it to. Then just as instantly, it "settles" to wrap snugly around you. No more constriction. It's time to sleep easy.
Why It's Better
Built Like a Bed
Built like your bed at home, with a sheet below you and a quilt above, the Zenbivy Bed gives you the freedom to sleep however it is YOU sleep best.
The quilt "floats" above you (even when fully zipped/clipped in) to give you complete freedom to move around during the night without the fear of feeling trapped. The hood is integrated with the sheet to insulate your head without the constrictive mess of toggles and cords.
Easily Regulate Your Sleep Temperature
Lots of bags work when it’s cold out, but how many also work when it’s warm? The Zenbivy Bed’s innovative 2-piece design allows it to adapt to a wide range of temperatures. A hot sleeper in need of cool relief has the freedom to easily kick their arms and legs out as needed. The convertible foot box can be vented or opened up completely flat for use on warmer nights. On cold nights, the foot box can be cinched and the quilt sides zipped to the sheet to fully “tuck in” and prevent all possible drafts.
Premium HyperDRY™ Down
Learn more about down
Conventional wisdom would have us believe that synthetic insulations outperform down in wet conditions, but conventional wisdom is wrong. While it is true that synthetics will insulate better than down when they are wet, it's also true that synthetics soak up water. Down is naturally hydrophobic. It's simply much harder to get a down bag wet in the first place.
We use premium HyperDRY™ down from Allied. This is the best down you can get. It is sourced according to the Responsible Down Standard (RDS) and each quilt comes with a tag that allows you to track exactly where your down came from.
Uncommon Fabrics
It's rare to see 50denier/20denier fabrics combined in a single sleeping bag. Most big brands match fabric weights, putting the coolest looking one on the outside. Zenbivy is different. Our liners use a relatively large 50d polyester yarn woven into Pongee. What does this mean for you? Ultimate softness and warmth to the touch. Our shell fabrics are made from smooth and ultralight 20d nylon with a simple Taffeta weave. The result is category-defining comfort at the lowest possible weight.
