NEMO - Disco™ Men's Endless Promise® Down Sleeping Bag (15°F/-9°C)

I vote for Nemo bags. I have 2 and love them. Perfect for side sleeping.

Get a disco 15 from Nemo. Only use kelty in the summers.

I have had a nemo disco 15 bag, two EE and now a Zenbivy 10 degree light bed with half sheet. The Zenbivy is by far warmer than EE and to the moon and back more comfortable than EE and the Disco. I was skeptical of Zenbivy but it is a quality product. I use a Ultra 3R exped pad for three season and a 5R in cold season.

Nemo for sure

Spoon shape is great, arm zippers in the boost just seem drafty.

I have a disco 15 and love it. Alternatively you can get a fleece bag liner to add some warmth that way instead of a whole new bag.

Just got back from Algonquin where the temps dropped to 3 degrees C. I was comfy in my fairly new -9 degree C Nemo down bag wearing long base layers only, but I felt if it got below freezing I would need some additional layers. Other commenters are giving good advice when they say a good sleeping pad makes a big difference, especially if the ground is already cold (not just air temps dropping at night). Don't trust temp ratings of cheap bags and aim for something with a rating 15 degrees below the coldest you could expect it to possibly get.

I have a disco and its pretty good used it like a quilt so often I ended up going for a quilt, Specifically a zenbivy, its also good, I set it up with one side fixed to the sheet and the other mostly free. Like sleeping in a bed.

Nemo sleeping bag with REI 2.5 self inflating sleeping pad works for me.

I'm a 230 lbs 6' 3" guy and this is a great bag for me. Used in 19F and it was warm. I am a side sleeper so the ability to turn helps a lot.

I might have been 10 of the mentions on the Disco 15 series. Oops.

I have a nemo disco 15 and feel it's worth the hype

Ouch, you are in a tough situation. You need a small sleeping bag, but have a low budget. Basically anything you buy is going to take up half your backpack. Your tent and sleeping pad will most definitely need to be strapped to the outside of your pack. 35L pack is really a limiting factor. Sure - the Nemo Disco is a fine sleeping bag. Better than the Forte for sure. The Kelty Cosmic is popular because it's cheap. If you can afford more, like the Nemo - go with that. I'd skip the 'zip together' feature. Don't limit yourself in that way. It sounds cute - but in practice joining 2 bags is not comfortable / warm. At least over the 18 years I've been with my GF. Hard to say more without knowing what brands you have a pro deal with and what temperatures you'll need to use the sleeping bag in (temp rating 15/20/30/40F?)

I think your pad is a bit over the top for the Rockies for 3 season but too much is better than too little. I use a 15 deg Nemo Disco 650 down had it for five years and have its perfect. I'm about to hand it down to my son and buy the new version, might splurge for the 800fp just to save to 100g! I do take thicker base layers in the late season.

Nemo disco down sleeping bag.

Tent: MSR or Nemo, sleeping bag: Nemo (the lightest warmest I've found) knife folding knife I'd use a Swiss army "Ranger" model, if its a folding knife sans that I'd use a fixed blade like a Pathfinder knife shop "scorpion or Kephart" the kephart is my favorite personally. It's always good to have multiple tools for sure sometimes they fail. Additionally if you're going to be in any remote areas take 2 ways to make fire whether that's 2 lighters or a lighter and a ferocerium rod doesn't matter. Ans water water water, and some way to filter said water. I've had situations even near or in towns where I needed water and had some but couldn't purify it and a metal container of you can canteen or stainless non vacuum single wall water bottle if you have that and fire you'll have purified water. Enjoy your walk sounds like fun to me

If your biggest concern about a sleeping bag is room for your legs to move without feeling constricted, I would try out Nemo or Big Agnes sleeping bags. Both tend to have wider profiles. Definitely go for a bag that is rated at least 10 degrees lower - preferably lower - than the temps you expect to sleep in. Theres multiple problems with layering with clothing like this, one of which is not the warmth specific factor but the breathability. One or two layers is one thing, but with all the listed clothing and then something like the picture on top, you're going to build up humidity near your body you can't get rid of, and you'll become even colder. Next, a sleeping bag basically creates a warm pocket of air around you. The insulation in the bag helps create and maintain this pocket. The more compressed this insulation, the worse it performs. With layering clothing, you compress the insulation, making it less effective. On top of that, insulation is minimal if not nonexistent at the seams. Some puffy jackets and "extreme temp" clothing gets around this by minimizing seams but there's almost always a few somewhere, which means no air pockets and no warmth. If I could recommend the best case scenario for you, it would be this: find a sleeping bag you can tolerate rated to a temp appropriate for your conditions, 15F at a minimum, best scenario a 0F. Dress in only your smartwool layers, and make sure you have a good pad/sleep set up underneath you.

I just got the Nemo Disco 15 and even in nights below freezing I was SWEATING. It's super comfortable though.

Your sleeping pad is fine albeit a bit heavy. I'm not familiar with Nordisk products but very familiar with Nemo. Given your budget I'd go with the Nemo Disco instead of the Riff. I've used a Nemo Disco 650 fill 15degF bag backpacking in the Canadian Rockies for seven years and I can wholeheartedly recommend this bag. It's warm enough for three season camping to below freezing temps (with the right base layer) and I've even used it winter camping down to -10degC. Yes, you want hydrophobic down as in certain weather you'll get more condensation inside your tent. I'm upgrading to the Nemo Riff as I'm handing down my Disco to my son. The only advantage of the Riff's 800 fill down is it's slightly lighter and should be slightly more packable. I'd get it if your budget allows but honestly I'd get the disco and use the savings towards a lighter sleep pad or some other gear upgrade.

Love my Disco 15. I'm 100% a side sleeper and I'm often riding up around the frost line even in the middle of summer where it still gets pretty cold at night.

I have that Nemo Disco 15 and it's killer but hoooooly cats does it sleep warm. I'm going to have to get something else to use in the summer.

Wife and I both have the disco 15 in women. The men costs more but they're both the same bag.

Nemo Disco is the way to go.

Disco is solid and light?

Im a side sleeper and a turner at 6'3" and 230 pounds. The quilt is great. However, if it is so cold you want an enclosed sleeping bag, I personally carry the Nemo Disco 15 large. I open this and use it like a quilt at times. https://www.rei.com/product/251886/nemo-disco-15-endless-promise-down-sleeping-bag-mens

I like the spoon shape of the Nemo bags. And, I'm currently using a wide deluxe pad from Big Agnes.

Quilts, semi rectangular bags (Sea to Summit Trek and Ascent Down) or the Big Agnes Sidewinder series are what you want. The Nemo Spoon series of down bags are also quite roomy. I sleep on my side. I use Hammock Gear Econ Borrows most of the time and I have a Marmot Col -20F bag for anything 20F and below.
