NEMO - Disco 30

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

This. I hate mummy bags. I move too much in my sleep. My Nemo takes up a bit more space in my pack but it is so comfortable and a good night’s sleep, where I can fully roll around in my bag, is worth it. I will never go back to a mummy bag.

Nemo for sure

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

I’m a stomach/side sleeper and love my Zenbivy quilt+sheet and their matching pillow system, but it’s quite an investment for a casual camper. I’d recommend looking for a cheaper quilt or even a rectangular sleeping bag on Amazon or Decathlon if you’re not looking to spend a lot. I was really unhappy with my spoon shaped Nemo sleeping bag. Even though it’s wider than a traditional mummy bag, it was still restrictive. There are a lot of other spendy quilt brands out there and most have already been reviewed on r/ultralight.

I love my disco. The shape is soooo much better than a mummy shape

Nemo Disco is the way to go.

Wow. Beautiful and easy to digest chart. Just picked up a disco 30 for my set up. Much more comfy and pack able than my old synthetic mummy bag. Love the wiggle room

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.

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?)

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