Big Agnes - Lost Ranger 3N1

For cheap, no. https://preview.redd.it/crlfe5zr9u1g1.jpeg?width=447&format=pjpg&auto=webp&s=528fa1c294cba5226b5f77d7a984a5ee5ee7ce1b Though, a system bag like the [Big Agnes Lost Ranger 3n1 0](https://www.rei.com/product/245987/big-agnes-lost-ranger-3n1-0-sleeping-bag) will get you awful close if you add the [Outdoor Research Helium Bivy](https://www.rei.com/product/203558/outdoor-research-helium-bivy). This is what I use. You could also build a similar system that is a bit safer from a 40 degree top quilt like the [Enlightened Equipment Revelation Apex Regular-Wide](https://enlightenedequipment.com/revelation-apex/) and any 20 degree Down mummy bag like [Mammut Comfort Down 23](https://www.rei.com/product/247720/mammut-comfort-down-23-5c-sleeping-bag)

Well in the Big Agnes system, the quilt is mostly for warmer weather, where that is less of an issue. Also, what isn’t obvious from quilts is that they actually deal with tossing better than folks expect. The key is that to “Collar” is oversized like a big draft collar on a traditional sleeping bag. Quilts like the Zen Bivy, and the above bag completely negate the issue of drafts coming in the side by by zipping or climbing the sides down. This makes means drafts can only come in the top. Cinch them up before bed and don’t worry. I bought the old UL version back when they offered a 800 fill power version. Kept the whole system below 3lbs.

Big Agnes Lost Ranger 0F Sleeping Bag and Pad. I can adjust accordingly with this bag because its two bags in one really. You specified camping and this is a great camping bag. I got it cheap a couple of springs ago. I like it.

We use a Redverz Attacama tent. [https://redverz.com/](https://redverz.com/) It is three person tent, with plenty of room for gear. It is absolutely waterproof. Assembly is not especially fast, but is uncomplicated. Having two people helps. It is tall enough to stand in and the vestibule/garage in enormous. While the "garage" is marketed and completely capable of holding a motorcycle, I never seen anyone actually put their motorcycle in it. It packs into a 50 liter dry bag with some room to spare and weighs 14 pounds. I carry it on my passenger seat.

For sleeping, I'm all in on Big Agnes system. The Big Agnes "system" uses a sleeping bag with a pocket in the bottom to hold an insulated, inflatable sleeping pad. There is no insulation in the bottom of the bag, that pad is the insulations. It is a great system and you can never roll of your pad. Get the "pump house" to inflate the pad.

I’ve got it and like it. Used down to -8c and that was its limit. Also use it combo with a quilt instead of the bag. As a side/front sleeper, it comes with a front zip bag which works well for me.

As it’s 2 layers with quite a bit of inner/outer layers between, it’s less likely to ‘wet out’ all the way through than a single layer. I’ve had the outer wetted with condensation and the inner bone dry.

As mentioned by others, rather than getting those heavy square bags you could opt for a down quilt. By the way you should make sure that you are actually a warm sleeper also out in the tent. I am a warm sleeper at home but when I an camping I am still getting the chills every now and then even if the comfort rating of my sleeping system is on point. The thing is that humidity and wind play a huge role on how the heat is sucked away from your body. By the way, even if bags are ISO rated, every company has its own standards (by the way even industrial production has certain variations in build quality and material). So, rather than trying to pinpoint the exact temperature your are going to sleep at that night, you could be better off playing it conservatively and go for something like a 0C bag with vents and double way zippers so that you can adjust your temperature.

Yes quilts are very popular nowadays. Right now I am using a hybrid setup, check out Big Agnes’s Lost Ranger lineup. It is made of one quilt-like piece and a mummy bag too, so that you can use the three setups: only quilt for 10C, only mummy (designed specifically for those who toss and turn a lot) for 0C and the two together for -11C. I love it!

From years of bikepacking in the Highlands, I've learned from bitter experience that you can't put a price on a warm night's sleep. I'm a side sleeper and I use a Big Agnes Lost Ranger 3n1 and I love it. I've slept out in temperatures down to -10 and been lovely and toasty warm. Have a look on Sport Pursuit dot com , they're on sale for £200 down from £400.

Kelly cosmic down bags are amazing bang for buck. REI has generous return policies as well, so if you get into a bag you don’t like, you have the option to return it for a year. More expensive bags/huge discounts don’t necessarily mean they are going to fit your needs. I currently sleep in the Big Agnes Lost Ranger, which is a 3in1 sleep setup. It is a quilt and a sleeping bag, which means you can sleep with just the quilt, just the bag, or if it’s cold enough you can nest the sleeping bag inside the quilt. It’s on the more expensive side, but it could be beneficial looking into a similar setup. I would however recommend investing in a nice sleeping pad that has a decent R value. I currently sleep on the Big Agnes Rapide SL Insulated (regular) and I LOVE IT. it comes in all different types of widths and lengths. I’ve slept on it for 2+ weeks in the Yosemite side country and I’ve never had a single issue with it. long story short, i’m a huge fan of the Kelty Cosmic Down line. there are also a few REI branded bags that may be worth looking at.

Four season can be difficult without knowing your temps. However, Big Agnes Lost Ranger is a 3 in 1 sleeping bag. You can use each part separately or combine them for additional warmth. [20% off in resupply right now.](https://www.rei.com/used/p/big-agnes-lost-ranger-3n1-0-sleeping-bag/203947)

I use my 3N1 from - 30 C to + 30 C. Admittedly I don’t have a ton of exposure to other gear, but it fuckin’ rocks from my experience. Also don’t really use it in +30C, it’s just there, don’t sleep with it on.

Having tent camped for years, then hammock camped for a decade, and recently gone back to ground I can honestly say this: quilts for hammocks, bag for tent. Quilts are too much work with a sleeping pad. You are better off getting something like a Big Agnes sleep system bag and pairing it with a pad. Much easier, and less drafts

I have been using a Big Agnes down bag. I think it was in the “ranger” series. They change models every few years. But stick with the “sleep system” bags. They don’t have a bottom side similar to quilts, but they stick to your sleeping pad much better, and wont let drafts in when you move around. Only issue with their bags are the temp ratings are not the best. But I mainly tent in warmer temps and save the hammock for really cold winter temps. (I went back to ground because I finally got a dog to take on adventures, and I want him safe from mosquitos and what not at night just like me)
