SynMat Hyperlite Duo

The Exped pads are far and away the best. Comfortable, quiet, reasonable weights, and has two separate air chambers so one person moving doesn't disturb the other too much. They are not rectangular though, so if that's a hard requirement, they might not work. Pads I've tried * Exped Dura 5r Duo Medium (current go to car camping/winter double pad, heavy though) * Exped Ultra 3r Duo Medium (current go to backpacking double pad) * Exped Synmat Hyperlite Duo Medium (borrowed to try out before getting other Exped pads) * Big Agnes Rapide SL (returned, too thick and felt unstable with two people, especially with one air chamber) * Kylmit Double V insulated (sold, not very comfortable, not as warm as it should be, heavy) List of pads I haven't * Nemo has the Quesar, but it's quite heavy for the warmth and durability. * BA has the Divide, but it's really heavy * Paria has the Recharge DW which is heavy but has an rvalue of 4.7 and is cheap

I don’t know what mats you’re talking about, as my appreciation comes for the Synmat Duo that only has baffles inside. I think the same of the Downmat. Agreed tho, they let me sleep like a little lamb in the backcountry. 😴

I floor slept with my Exped and a wool blanket, same results! My body evened out and woke up feeling much more refreshed.

cancel all these and get an Exped

My current pad is an Exped Hyperlite (discontinued) with an R value of about 3.2. I have used quilts for 15 years. I do not tie the quilts to the pad. Always a side sleeper, unless I take my hammock. The quilt you use must be wide enough to tuck. I am claustrophobic, so need to get out easily. And I always sleep warm, tucked in. Many nights were below freezing. Big Agnes bags that have the pad pocket seem to lead to cold people, because the pad holds the bag wide open. Having the ability to tuck whatever you use for insulation around you is important because you warm up the insulation with body heat, air space will make that harder.

If you get a Big Agnes it will squeak against the tent floor all night when you move. I use Exped. Not completely noiseless, but built differently than the Neo pads and not a Big Agnes. I have a discontinued Hyperlite, will replace it with an Ultra when it develops too many leaks just as I did the Synmat. I wish they still made the Hyperlite.

I have a previous back injury. I find the Womens S2S Etherlight to be the most comfortable, though the least warm. Next for comfort is the Nemo All Season, as well as the Nemo Tensor. In comfort, they are both just slightly less comfortable than the S2S. Both are warmer than the S2S. I have used the ExPed Hyperlight pad for about 40 nights. I believe this pad has been replaced with the newer version. Mine was a 2.8R value. For me, the warmth was equal to the S2S pad. It was not an uncomfortable pad. It just wasn't as comfortable as the S2S and Nemo pads. I tried the Thermarest NeoAir Xlite. My lower back ached when I used the pad. It just didn't have the support I needed. I wish I could use it as it has great warmth to weight ratios. I used the wide versio pads for each of these, though the Exped was a mummy MW version I would assume what is comfortable for me may not translate to you as your back injury may be different than mine. My injury involved the lower back. I have slept in a hammock a few nights and never experienced back pain.

I have an Exped Synmat and it's quite comfortable. It's more "air mattress" than my Thermarest Prolite Plus but more comfortable. So much so I'm insisting my wife use my Synmat mattress instead of her existing Thermarest on our next trip. I can handle the lesser one (I hope). I think basically if you're spending some money it's always going to be more complicated than "air mattress". I think OP means a classic vinyl sack filled with air. They tend to have poor support, zero vapor management, and are cold (because air convection inside the mattress takes all your heat and moves it to the ground).
