Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I don't have the 15, so I can't directly compare, but yeah I have no trouble getting the 30 into an 8L bag. There's not much room leftover, but it fits. I also have a Riff 30 and it fits as well.
The Tempo is a larger bag than the Disco or Riff. According the specs at REI, it weighs almost a full pound more and has a compressed volume of over 8L. I'm not a guy that can ever get anything packed away nicely or back in the box it came in, but even I had no trouble just cramming either the Riff or Disco into the 8L compression sack. They're currently on sale at REI thru next week.... 😈
i vote get a compression sack for the sleeping bag and another for the tent. you’ll save so much room compressing them down. ditch both sets of cutlery, go for one long spoon. are you seriously tied to the jetboil? if not, get a smaller stove (pocket rocket works well imo) and get a smaller gas can if you can. stove, gas can, and lighter should all fit in your titanium cup, or at least a few of those items. ditch the lantern, use your headlamp.
maybe it’s a skills issue on my part, bc even our tempo 30° do not fit in a smaller bag than 13L. and let’s be real i do NOT need any more excuses to buy more gear 😂 very glad you can get it down in those bags!!
I have a Nemo Tempo 35 that I use for car camping and sometimes paddling. Super comfortable shape, and l do find its comfort rating of 40f to be in the ballpark. If forecast is for below 40f, I bring a different bag or plan to wear a puffy or fleece.
I have a Nemo in 35 and 20 and backpack in the Rocky mountains. If I had to pick one, I'd buy the 20. I do love the light with 35 when I can get away with it, but I'm often not brave enough to take it, even in the summer.
FWIW I camp 3 seasons in CO at high elevation with a Tempo 35. Have had nights in the mid 20s in fall and still slept great. IMO the 20 would be bulky and hot... but the campfire bourbons definitely helped keep me warm as well 😉
As a warm sleeper I would absolutely die in a 15 degree bag if it's 30+ out. I would have to fully unzip it and then struggle to regulate temperature all night. The Nemo gills help a little but they do not help enough if you're a warm sleeper and it's 15 degrees over your bag rating. I have a Nemo 35 degree bag that I use and I've never been cold in it even though the comfort rating is 40. If it's 50+ degrees out it gets too hot. 35-50 is definitely the sweet spot for it. Personally, as long as you're not in dangerously cold conditions, I'd always go with a warmer bag and wear extra layers to bed or have a backup quilt to throw over it in case it actually gets too cold. I've had way more camping nights ruined from having a bag that's too hot than one that's too cold. You can always add layers but once you have to fully unzip your bag because it's too hot you're in a tricky place with temperature regulation for the night. If you're a hot sleeper do not buy a 15 degree bag if you're basically only camping above 30 degrees. I would be looking at a 35 and then also buying a cheap synthetic camp blanket as an extra layer when needed or an only layer for nights that are 50+
