Mattresses / sleeping pads

^{Thanks for the response. Seems he best option is to go for an R Value of 6+}

Means more saving but better in the long term.

Yip, I have just bought a Neo Air X Therm, supposed to be the best on the market at R5.7 Very expensive, but hopefully will last me until the end of my life...has a life time guarantee.
Without decent insulation even the best sleeping bags will fail.

Wow, an R value of 6 is very high.

I use a Thermarest sleeping pad, think it's called the Ridgerest if I'm not mistaken. It has an R-value of 2.5 and it's been sufficient for all my berg hikes. Coldest night I've had was -14 deg in the tent at Giants Castle one night in the snow, and I was fine. I guess everyone's experiences cold differently, but for the berg 6 is high. if you want to err on the safe side then this number will be perfect though.

Hi All
Looking for a new sleeping mat R4-6 rating, about 6cm deep.  
Richard said he had a First Ascent Ultralight Insulated Mattress for a year as this didnt last beacuse of leaking seems. They now have a Ultralight Insulated PLUS Mattress.  Has anyone used this?  
Naturehike has a R5.8 ultralight anyone have this or have used it?  
Any others ideas?

I have the Naturehike. I've not used it on a hike yet, but I have slept on it for a few nights at home.

So I can't comment on the thermal effectiveness etc, but I can mention, that to me at least, it's very comfortable. I have the regular envelope style pad. I have used the R3.5 version on a hike in the Berg, it had a slow-leak, and Naturehike replaced it for me (and I paid the cash difference to get the 5.8). It worked fine on the hike apart from the slow leak.

I don't have much sleeping pad experience for comparison though. My previous pad was a k-way exp something (a long yellow one). I find the naturehike pad to be much more comfortable and warm. I really like the quilted square style pad.

hey @Wandelaar!

How has that Naturehike Mattress held out? I'm looking at getting one too. Don't want to spend much on a new one right now and think it may be a nice pair with my FA egg crate pad.

So, unfortunately that pad failed the night before we were to start hiking the Tour du Mont Blanc. The internal "quilting" failed while I was sleeping on the pad and I woke to the "gunshots" of a series of explosive failures causing the pad to "pop" up in sections. Luckily, we were still in Chamonix, so I could buy another one there the next morning. Unfortunately, we were in Chamonix, so I had to buy one there the next morning $$$. Ended up replacing it with a Rab Ultrasphere which was way too expensive, but the only one they had there. It's been holding up well though, and it's warmer, lighter, and more comfortable than the NH pad. It is VERY ultralight though, so even though I'm babying it as much as I can, I don't have high hopes about its longevity.

Check with Drifters, they are starting to bring in the Nemo Eclipse pad which is cheaper and more comfy than my Nemo Tensor. It's 40D fabric and a lifetime warrantee..
