Best thing for sleep is a double pad. You can sprawl out and never fall off. The exped duo long and wide is amazing. Also have the nemo quasar double, but the exped is lighter and more comfortable. Best pillow is thermarest.
That's a hollow tube inflatable pad. It's also a *wicked nice one*. IDK where the optional layer of Primaloft goes, but since they call it a layer, not fill, I think that it's safe to guess that it's not inside the tubes. So those tubes are super comfy, but convection currents inside them will carry warmth from your body to the ground. I suspect that's what the Primaloft is for, and that it goes on the bottom. If it's on top, that probably works as well. I'm sure the manufacturer's R&D testing is far more valuable than my speculations. I also suspect that the Primaloft will be a lot lighter than a close-cell foam pad, and might well be the better option.
quasar is like a mattress at home. Weight and bulk worth the better sleep
Nemo Tensor is a very solid pick. I have the Nemo Quasar 3d insulated which is heavier and a lower R Rating. But my god it is so insanely comfortable.
The comment for brandoldme was spot on. I personally have the NEMO Quasar insulated pad and I absolutely love it. Nice and thick and I’m a heavier side sleeper so it’s the only one I’ll recommend for the best bend of comfort and weight. Not the smallest or lightest on the market but it will definitely still in the backpacking category.
Nemo Quasar 3d Insulated is an option. A few size and width options and a very thick pad. I sleep quite comfortable on it.
