Static V Long

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.

My car camp pad is an exped mega mat, wonderful. Saw a cheaper version at Scheels by Lightspeed? Dense foam with air and it holds well. For backpacking, I need lightweight and use a Klymit5, love it, but 3 nights on it I’m wanting a hotel.

My favorite is the klymit static-V pads, they make extra wide and doubles, insulated or not.

Did they change the valve? Both mine have twist valves.

Stacking generally works in really simple formulas. Using (2) R-2 pads stacked will get you about an R4 insulation, which would be great for this situation. I don’t know if you’re driving or backpacking or what, but you might consider an inflatable pad paired with your current pad. It’ll pack smaller, should be more comfortable, and since you don’t really need a high Rvalue air pad it wouldn’t need to be a huge budget investment. I generally don’t recommend pads from brands like Klymit due to their lower R values, but something like a Static V paired with the foam pad should be warm enough for above freezing and would be more comfortable and more packable.

For £50 you’re not going to get the same warmth as your old Ether, but you can get something comfy and reliable like the Klymit Static V If you want something easy to grab in-store go to a Decathlon and look at their Trek series pads which are pretty affordable too.
