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 have a ZenBivy "Light". It's quite comfortable and does work as designed. But the extra stuff adds a little extra weight. Maybe worth it in cold windy weather. Not worth the weight in warm weather. They do now offer an "ultralight" quilt which I have not tried. If I were to buy a quilt again today, I'd probably try an Enlightened Equipment custom. If the ZenBivy idea sounds really good to you then consider it. For ultralight, you should consider the weight. You don't need to user their pads (I don't). Just order the sheet size that fits your pad size.

I don’t have much of a recommendation for bags. We use sleeping quilts…and if you want lightweight check out enlightened equipment as they are on sale right now. They are a little bit more than your budget but really lightweight. There’s also Zenbivy as well for quilts (we both have Zenbivy and I also have an EEquilt for summer). They are also on sale right now. I do want to point out (as I am 5ft tall and my husband is 6ft tall) that if you are backpacking in a cold climate I wouldn’t recommend a double bag. Even if you get ones that zip together they won’t fit well bc yours should be smaller than his. We got a double bag once and we used it on one trip (car camping) and never did that again. We FROZE. You need your bag to fit closely to you. For it to fit my husband it had to be big enough for someone 6’5”. So that left a foot and a half of dead space at my feet. It was an AWFUL idea. So when we got home I got me a short version bag (up to 5’6”). As far as pads go we like thick ones bc we both can’t sleep on thin ones. I just bought a Featherstone Calcatta and a Big Agnes Rapide and love them both. They are 4.5 in thick and 4.25 inches respectively. Big Agnes does make a double pad (I think it’s the rapide as well) and I think it weighs 2.5 lbs so that could work if you want a double pad.

Another +1 on the zenbivy

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.
