Disco 30

I have the Nemo disco 15. It is very comfortable. I wouldn’t use it on a warm summer night, but it is fantastic during the shoulder seasons, even if it’s not below freezing. It packs very small. The only negative is I purchased the regular size and I am exactly 6 foot. It’s a bit tight on me as a result. If you were 5’ 10” and under, I think you’d be quite comfortable.

If you sleep cold or don’t mind opening it up and using it as a blanket when the weather is too hot then maybe the 15, As others have stated, the 15 might be hot so the 30 is probably fine for that time of year. Note I bought the 15 because I go when temps are often 28-36° at night. I looked up the weather. “In August, the Pemi Loop features warm, humid days (70s-90s°F) in the valleys and cooler, windy conditions (60s-70s°F) on the ridges, with a high risk of afternoon thunderstorms and fog. Hikers must pack for rapid changes, prepare for heavy rain, and start early to avoid exposed ridge lines during storms.”

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

I love my Nemo Disco 30. I get too claustrophobic in mummy bags, but the Disco is perfect for me. It has enough room to move around a bit, I can even side sleep if I want. The extra space is worth the little bit of extra weight imo

you will ROAST in the 15 for most nights being 60-70. You could do the 30 and then get a liner for the colder nights.

honestly I think you'll be ok. I have a Disco 15, I took it on an overnight backpacking trip last May (in the Finger Lakes region of NY) to test it out; it went into the 30s overnight. I was roasting in my underwear. I've since picked up a Disco 30 (found it barely used on FB marketplace) which I think will be more appropriate (and it's smaller/lighter)! I have an Enlightened Equipment quilt too but I can't manage with that during shoulder season. I also have a sleeping bag liner so I can modify bag warmth that way. This year I was going to really dial my sleep system by temperature but then I tore my stupid ACL skiing. Maybe I'll get to do some canoe camping at least.

I'm a 'rotisseree' sleeper, turning the full 360degrees throughout the night because of pain. I love my Disco 15. I'm thinking about getting the Disco 30 for camping in warmer weather.

I'm a rotissery sleeper because of aches and pains. I really like the Nemo Disco bags. Very spacious and I like that you can get super cozy if you need to or unzip and use it like a quilt.

Nemo Disco 30 is perfect. I always bring thermals to sleep in and if you get cold just put your jacket on but give never had to. You’ll be good.

Nemo Disco bags are great for side sleepers. Unless you truly winter camp... the 30 is fine. Just sleep in fresh dry socks when going to bed, and a base layer. Easily covers you down to 20 degree lows.
