Testing the Best Winter Sleeping Pads (Thermarest v Sea to Summit)

I've been busy testing the best winter sleeping pads from Thermarest and Sea-to-Summit, and here are the results.
These top-of-the-range winter pads will keep the camper warm, even in the coldest conditions, but how do they compare? What's the difference between them?

Summary:
I really liked the Thermarest as it's so light and packs so small, but the Sea to Summit was more comfortable for me - I am a heavy side sleeper, so maybe you'll be better off with the thinner Thermarest?

Great video! I’m looking for a similar video comparing the XTherm and the Nemo Tensor Extreme.

Owning the Thermarest Xlight and the Sea to Summit etherlight extreme I would not necessarily say I like the Thermarest valve more. I find that the sea to summit one deflates a lot quicker and also allows the pump sack to preform faster and does not have the tendency to pop off as the winglock valve sometimes does. Also you can manage the pressure on the sea to summit valve by pushing the little knob inside the ‘inn’ valve. Something to keep in mind with the sea to summit valve is when you want to remove the pump sack you want to brace the ‘out’ valve because it comes loose pretty easily, dumping all the air you just pumped in the mattress very quickly.

I think a better comparison would be the x-therm max 25 wide version. It would be more comfortable than the mummy version in this review.

I am looking for winter pad and your video notches me towards the Sea to Summit Etherlight XT Extreme. Unfortunately I had Warranty issues with my Sea to Summit UL Self-Inflating Sleeping Mat. After a back and forth during a whole month the solution they offer me is to cut my mat in half and sent a picture so that they provide me a new one. Not a very ecological solution a outdoor lover would strive for. The shitty experience I had with Sea to Summit Customer Service is more than just that, enough for a 4min video. Daniel, you wanna know more about it?
