I’m a 100% side sleeper, so I went with the regular NeoLoft because I don’t usually need the extra width. The NeoLoft is the only inflatable pad I have ever used where the edges collapsed. Aside from that, the pad was great and I was bummed that it didn’t work out for me.
My fav pad for comfort is actually the Big Agnes Rapide SL, but they use their own temp rating and estimate the R-value to be 4.8. I think that’s a little generous based my personal experience with it, which is why we switched to the Exped Ultra line.
Keep in mind that if the NeoLoft truly sleeps cold (per reviews), it may be worth comparing against the Rapide SL since it sounds like they’d be comparable in size, thickness, and warmth. The Rapide in Regular-Wide is 1” narrower and 1/4” thinner, but it’s also 7oz lighter, packs smaller, and is $40 cheaper.
Finding the Ultra 7r allowed me to narrow my pad use down to a single option. For me, personally, the blend of features and comfort best match my preferences over any other pad. We only backpack in cooler/cold weather, so the high R value is a non-issue.
Best of luck on the search for your Goldilocks pad. Remember to update your thread with what you pick and let us know why. I’m curious and I suspect others might be, too.
