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?

[Exped FlexMat](https://www.exped.com/en/products/sleeping-mats/flexmat) and [FlexMat Plus](https://www.expedusa.com/products/flexmat-plus?variant=42267057029337)\* were available in LW size (77"x25"), now replaced by [Flex 1.5R](https://www.expedusa.com/products/flex-1-5r) and [Flex 3R](https://www.expedusa.com/products/flex-3r)\*, still in the same sizes. [Thermarest RidgeRest](https://cascadedesigns.com/products/ridgerest-classic-sleeping-pad?variant=41316889657478) Large is also 77x25" inches. [Seek Outside Matty McMatFace](https://seekoutside.com/matty-mcmat-face/) is 80x40". [Gossamer Gear Thinlight Rolled Wide](https://www.gossamergear.com/products/thinlight-foam-pad?variant=42879197511734) is 58x25". Mountain Laurel Design Goodnight is available in 80"x40" in both [1/8"](https://mountainlaureldesigns.com/product/goodnight-eva-1-8-foam-pad/) and [1/4"](https://mountainlaureldesigns.com/product/1-4-foam-pad/) EVA. (\*) The FlexMat Plus has large dimples that some people dislike when new. They flatten some with use, or can be covered by a thin EVA pad (Thinlight/GoodNight/Matty McMatFace).

both are solid options but if you want the extra width for side sleeping, you might lean towards the Exped 3r. it’s got better insulation too which can be nice if temps drop at night. good luck on your trip!

i'd go with the Exped 3r. the extra warmth and comfort for side sleeping will be worth it on your first trip. good luck out there!

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.
