I appreciate your work. I've got the Exped Flexmat Plus (M) and have been looking at the new Flex 3R. I think that Exped might have some problems on their website with regards to the specs on this new pad and I suspect that you also saw this when putting together your information. Something just doesn't seem right. Both pads have the exact same dimensions (length, width, height) but have different weights. Now it would make sense that the newer pad with the higher R-value is probably heavier. But wouldn't the thickness need to also be greater?
Not sure where you are located, but I have a Flexmat Plus in long/wide that I have only used for 2 nights that I can sell (I'm in the US). I like the pad, comfort wise. I just chose to replace it with size medium Flexmat Plus.

That makes sense to me. It’s basically the same stuff as typical R1.8 accordion pads, but with larger dimples. I don’t see how big dimples add an entire R digit, especially when compressed by a human.

I have a cot + 1.5" foam + EXPED FlexMat Plus, great for back and side sleep. I have chronic back pain and sleep well. $23 for foam on Amazon [https://www.amazon.com/dp/B07999TQWB?ref\_=ppx\_hzsearch\_conn\_dt\_b\_fed\_asin\_title\_2](https://www.amazon.com/dp/B07999TQWB?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2)
I have a Naturehike ultralight low profile cot and put an Exped Flexmat Plus on top and then a 1.5" foam pad on top of that. But I'm middle-aged with a back injury. I sleep great on it, both on my back and on my side. I car camp, so weight is not an issue. If I did hike, I'd carry the Exped mat.
Having just tried out a FlexMat Plus at ~-4C (24F), I feel like their new R-value of 2.8 is kind of optimistic.
I actually gave up and went inside at 5 AM because I couldn't sleep from the cold. I forgot to bring my 4mm EVA mat, which I had planned to put on top, and which I think would have made a material difference to my comfort.
Exped flexmat plus is long/wide 76x25.6 with a 2.2 r-value. Bulkier but worth it. https://www.expedusa.com/products/flexmat-plus?variant=42267057029337&country=US¤cy=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gad_campaignid=22565769503&gclid=CjwKCAjwp_LDBhBCEiwAK7FnkgEOGqcPsqOWPqdF4VD70u3w1aYhvaJ04U21XuKQQNPNXqAEfHPLohoC3MMQAvD_BwE
Yes but the Exped Flexmat PLUS is S Tier. Most comfortable CCF pad on the market.
Flexmat Plus, the best.
Exped Flexmat Plus is the king of CCF. 1.5 inches plush goodness. Cut down to torso and combine with Thinlight.
I hated it like hated hated it.
Phenomenal mat! This is the one I'm currently using. Try a couple nights car camping with it, or sleep out in the backyard, before taking it on your long trek. Works for me, no inflatable required.
