Rab - Ionosphere 5 Sleep Pad

So my main mat is the Rab Ionosphere 5 mummy, and while it's super warm (r of 4.8), it's definitely not the most comfortable or cheap so I wouldn't recommend it. I recently bought the OEX Flux 7R for about £60ish for my partner as shes a cold sleeper. I've tested it out on a few wild camps recently and I have been very impressed. Not quite as warm as the Rab, even though the r value is supposed to be 7.2, but its by far the most comfortable mat I've used, and plenty warm enough for most UK conditions. But from a personal pov, I don't really trust the OEX range from a quality standpoint so I don't know how long it would last. Time will tell. But given this, if comfort and warmth are priority, Sea to Summit does some very nice looking mats in the same style as the OEX, and should hopefully be better quality, so I would be tempted to try one of those.

Side sleeper here, use the Rab Ionosphere 5, works well

I had the RAB ionosphere (4,8?), the yellow one of the same line. After about 40 nights of use, it would not stay inflated for longer than 2 hrs, checked it for leaks etc.  Got my money back and am now rocking Nemo tensor 4 season (we're now 4 nights in, we'll see!)

We just bought Rab Ionosphere pads and love them. Bonus: Rab is not a US company. https://rab.equipment/ca/sleeping-bags/sleeping-mats
