Inertia X Lite

I use a Klymit Inertia X Lite for bike packing and I really like it so far. It's a 3/4 length and weighs 173 grams. I bought it specifically for the packed size, because my switchback was too annoying to fit into my bike packing rig. It's probably a little larger than my fist when packed down.

Mostly a side sleeper. It’s pretty decent, better than a switchback, comparable to an Xtherm (in my opinion at least. I always have preferred firmer mattresses, even in general life). I felt I kind of slotted into the pad because of empty spaces, so I didn’t feel like I was going to fall off, like I usually do with inflatables.

klymit inertia is pretty dang light. light enough that i went and got one to play with.

Im going to visit this summer 2 times in Lapland. To explore west side of Geaidno and Rastigaissa area to the Halkovarri. Im living next to Nuuksio National park, so if u want hiking friend for weekend, just write private message. Its is safe to hike around year, even in -20°C. But in mid winter naturally have to use skies. Last weekend I was overnight in Vääräjärvi, in East Nuuksio. I had Carinthia Survival dual layer sleeping bag, Klymit inertia, Under Klymit Inertia i had Kaira's Thermofolio Extreme foam pad. On top of Klymit i had Kaira's normal thin foam pad with 10 mm structural holes. If there comes dewpoints, it goes to thermofolio foam bad surface to keep my sleeping bag more dry. In Summer I have naturally different sleeping bag and only Klymit Inertia.

Anyone feel intertia series are backwards? Why are my hips and shouldes exposed but my feet and head so supported? Feet don’t matter and head has a pillow?

1. foam pads outperform their ASTM rating. I personally feel comfortable taking my 2R CCF pad down to freezing, and a number of people agree with the assessment that a CCF pad is 3 season capable. Most of those generic egg crate z-lite knockoffs are 1.7 to 2R which is fine for summer or even 2 season conditions. Sometimes you get lucky and get a true 3 season pad for cheap. 2. Your numbers are a bit conservative, but that also depends on location so it may be right wherever you are. For air pads, I’d agree somewhere near 2 is fine for summer, like the Klymit uninsulated pad is 1.9R and a fine budget summer pad. Thermarest neoair xlite is the UL 3 season gold standard at 4.8R. However as stated, CCF sleeps warmer in the real world and a 2R CCF pad will sleep just fine in a lot of 3 season conditions. for example I used a z-lite for every step of the AT and now a switchback for the Oregon coast trail, a 1000 mile LASH of the PCT, and the PNT. to OP, the main issue is do you find CFF egg crate accordion pads comfy? if you do, it is like unlocking a cheat code for putting together a cheap, light, comfy sleep system. I’m lucky in that one of these pads is enough for me but I only recommend it if you aren’t sacrificing sleep.
