UltraLight Insulated Mat

Of those I have experience of the S2S ultralight, Vango Aotrom platinum and the Rapide SL. The differences between the S2S and the Vango are minimal, S2S better feeling materials and more comfortable, but colder, noisier and more expensive. The Rapide SL is much more comfortable and warmer than both. My partner uses the Rapide SL and loves it, I personally use a Thermarest Xlite and whilst not as comfortable as the Rapide is considerably lighter and noticeably warmer. If you have a store anywhere near you can try out a few I highly suggest that.

I worry sometimes about what "doing some research" means. I wonder if that included searching a relatively obscure web site such as [www.reddit.com/r/ultralight](http://www.reddit.com/r/ultralight) for the results of previous identical or nearly identical research? 3.1R is not warm enough for me below freezing temps, but the other two would work for me. Do you care about price or weight? I would not use a pad with thermal welds like the Nemo because I think they are prone to leak failures like this: [https://i.imgur.com/CctgN7p.mp4](https://i.imgur.com/CctgN7p.mp4)

Holy moly! That's some good deals! I have the Sea to Summit Ultralight Insulated Regular Sleeping Mat. Great for 3 season camping. Tempted to get a spare at £80

I like the STS UL Insulated in XS. For me, the low height is comfier than the balloony X-Lite

Exped Ultra 3r Mummy or Sea to Summit Ultralight Insulated in small (168 cm). Hyberg Slumber 400. Both a scant few € over your budget limit - but in the end you could just resell them for most of what you paid

I've been fine with an R2 CCF down to 20f limit. A 3mm ccf added makes it significantly warmer and more comfortable. A short accordeon and full length 3mm is a great combo. For an air pad, the Sts Insulated with an R3.2 is a limit for me. XLite around 4.5 is cosier and more than enough imo. I prefer the STS for comfort

I’ve had the original S2S ultralight pad for probably longer than 10 years now. It’s a beast. I can imagine the newer models are even better.

\[I don't race\] My go to is StS UL Insulated which isn't as light as TaR ones, but the insulation greatly reduces the convection losses that are present in pads which rely only on mylar walls within the pad. Few years in and still no sign of wear nor leaks on the welds. Do you use quilt or a bag? If the latter, then maybe give a try to the Klymit Inertia X-Lite + current foam?

Check out the StS pads with that 'dotted' welding pattern. IMHO cracks showing up in the fatigued welds are more likely to be an issue rather than some punctures (unless you are really unlucky in some thron country).

I was like OP and had the Klymit but then switched to the Sea to Summit ultralight insulated pad (oval shape) a year ago and it’s been amazing. I used my Klymit again last month on a father-son trip and the difference in comfort is noticeable.
