  • Sea to Summit Etherlite Xtreme

    Looks like there is another option available for a packable winter mat
    The Sea-to-Summit Ether Light XT Extreme Sleeping Pad is an 4" thick winter sleeping pad that has an R-value of 6.2 for cold weather camping.

    Nice! I had to settle on the Pariah Recharge Insulated XL pad paired with a Z-Rest to get to a solid winter R value. I really like the combo, but it’s bulky for backpacking hot tenting. Not so much a worry with the toboggan. I think we’ll see more 6+ R value pads on the market…I hope.

      Have a look at Klymit. I got one on recommendation of two Sherpas.

        Never got on with the lighter weight Klymits that I tried. Found them not thick enough for side sleeping and a little cold. Maybe the beefier versions would be better? A great event for a future WCS would the an opportunity to try out different mats, even if just for a few minutes. Could some idea of comfort even if not insulation value.

          Cool idea for sure. I've had similar experience with my Klymit Insulated Static V. I've used it for years, and found it especially comfortable in my bridge hammock. But as a side sleeper, it was always a little underwhelming on the ground and not as warm as I had hoped. They did recently update the "reality" of the R-Value for their pads, if I recall correctly. I'm always suspect of a pad that relies on down to loft into the voids of a pad UNDERNEATH me. Especially no bueno when using a topquilt. Nonetheless, it's been a solid pad and I've never had a miserable night on it. Paired with a Z-Rest or similar CCF pad, I've been roasty toasty. My biggest gripe was probably the valve. I have the older style, which they've sense updated.

        My system is a military ccf, the Klymit, Canadian Army wool blanket, then my US military MSS, another wool blanket, then on top is my 4 point Early’s of Witney wool Trapper blanket. The Klymit has been good for about 10 years now, which to me is pretty exceptional. Previous was a Thermarest. Sometimes I will throw in a second ccf, and bring along some of that white sound deadening material used under hardwood floors.

          Found one of these on sale. I opted for the Women's large. I'm not sure why the outdoor gear industry stick to this kind of nomenclature, not very helpful! It's basically a same length as a men's regular but wider. First impressions are that it is very large when packed. similar to an Exped Downmat. Secondly that it is very comfortable. I've yet to test outside but will report back when I have more data.
