Zenbivy - Light Quilt Convertible 40°F Synthetic (2024 Model)

Am I backpacking or car camping? If the low is 41 and I don't think it's gonna dip any further, than probably something that goes to 30F or so. \* Backpacking would be my old Big Agnes Deer Park 30F long down bag, or might risk it and run the Zenbivy 40F synthetic quilt (but I am also a human space heater) and good wool baselayers. \* Car camping would be Big Agnes Echo Park 20F long, because I sleep like I'm in my bed at home in that thing. General rule is that most bag ratings are more or less their absolute LIMIT rating. A 30F will help you survive at 30F, and is comfortable around 40-45+ depending on what temperature you typically sleep at. If you sleep too warm like me, you'll be fine. If you sleep a little on the cool side, I would offset the rule from around 10-15 degrees to at least 20F bags.

Swconding my Zenbivy quilt. I have a 0° down and a 40° synthetic, and I love them both so much.

I love my 40 degree synthetic zenbivy quilt on the full length light sheet with insulated hood for late spring to early fall on my exped 5R sleeping pad. Comfortable, versatile, way better than any mummy bag I've ever used. I will likely add the 25 degree down quilt to let me push into colder temps when I can afford it (on sale).

I love my Nemo Tensor and use it year round. As for bag I have a zenbivy light quilt that is great for temperature flexibility. Mine is rated for 25F and works for me late spring through early fall. The new 2025 ones have a 10F option which will extend the usability. In the summer you can just use it as a light blanket and then sinch it up like a bag when the weather cools.

Whenever you see a picture of a sleeping bag like this and it looks extremely think/plush. They have inflated something inside to make it look that way. Zen bivy do the same. My zenbivy quilt is so fucking thin I can pinch my fingers from both sides and feel NO down in spots.

Look at Zenbivy. Having your feet free is their concept. It is a quilt that connects to you bottom sheet/pad. You can only hook the top and leave feet free or you can hook the sides of the feet but have the bottom open. Or just do one side. It's got lots of options for you to pick what you want. It's also made of down

Get a quilt and never go back. I love my zenbivy.

All you need is the quilt. If you want to fasten the quilt down which reduces drafts you need the sheet. You don't need their pad to make the rest work. In general I love my zenbivy and will never go back to a bag.

I started off with the Nemo Disco. I’m a side sleeper and that bag allows me to move around without the mummy bag feeling. My son is camping with me so he got that sleeping bag and I upgraded to a Zenbivy. Game changer. Sleeping quilts are awesome and pack down just as well as traditional sleeping bags. Keep an eye out when they go on sale, got my system for 30% off. I got the 0 degree and yeah, if it’s 50 degrees out I have to open it up. At 30 degrees I’m snug as a bug. Haven’t gotten below 30 yet.

I got a zenbivy sleep system for around £250 in January on sale

Zenbify fits the design you're asking about, but is above your cost by a decent amount. They are super comfortable though, and I love mine. Might keep an eye and pick up on sale/discount or with a coupon code. I'd generally recommend 2 sleeping bags/quilts vs a shared double unless you both tend to sleep at the same temperature. You can also get sleeping bags that zip together if you do want to share space but have the option for solo/separate use. That being said, Kelty makes good stuff so I'd trust their double if it fits your needs.
