To all ULers:

[Dogwood]

What is the highest R value lowest wt 20-22" X about 65-72" CCF pad? Don't want 1/2" thickness. Want to be able to roll and fold the pad.


I have to find that out first before I can analyze it from a wt, bulk, and warmth perspective if it's worth it to supplement a NeoAir Xlite Woman's R 3.9 20"x67" with the CCF pad and a .7 oz mylar sheet or just go with an Xtherm purchase with the mylar.


Thx for your input.

Easily good down to at least -10°F for me, although I don't know the R value: Cut-down Xtherm Max 71"x25" (20.4oz) combined with a 3/8" CCF 71"x23" (7.5oz) on top of the Xtherm.

I tested with a GG thinlight (1/8" CCF) and it wasn't enough for me. A Ridgerest Sol was too much insulation for me, thankfully, way too bulky and weighs nearly a pound. Goldilocks hard a work.

However, in an extreme situation where I'm going to be out a long way from a trail head, the Ridgerest might be taken because it would get me through the night if the Xtherm sprang a leak.

Not that I'm a true ULer (more like a VLer), but I echo cmoulder on the 3/8" pad along with an xlite (I dont even need the higher R xtherm) is good down to negative temps on bare frozen ground. I've cut my 3/8 pad down to 60", don't seem to need that extra 12 down at the feet, though I might put an articla of clothing down there in frigid temps. I think the 3/8 thick 60" long pad is right about 5 ounces, good insurance against a failure of the blowup pad and still have some R and softness to sleep on. I cannot remember where I bought it, had it for 5-6 years or so. I also trim the corners up high around my head.

I do also carry a 3/16 (measured) inch thick pad in the summer, I think about 2.5 ounces, for protection of my blowup pad and also makes a nice nap-pad along the trail mid-day.

Just what I was looking for. THX to both of you. I wanted some confirmation on what I too was already thinking.

I have a beat up 1/8" CCF pad cut down for under a Neo Xlite but am having problems finding a new 3/8" to buy. The GG 1/4" CCF pad is double wide for hammocking. Don't want to drop $50+ for what amounts to two pads about 19.5" x 59.25". I hear you Rob but I'm tall at 6'4" and this is for supplementing NeoXlite Short(47" long w/ 3.2 R value) and the NeoXlite womans(67" long w/ a higher R Value at 3.9 which I switch to deeper into the shoulder seasons and fairer winter temps). I want a little longer than 59.25" for this reason at those times.

I still would like to see noted some CCF pad R values.

[Dogwood]

I like the two of you are from cold climes getting out in such conditions and note similar pad set ups. THX again.

You might try a cheapo mylar reflective ground cloth at about .5-.7 oz under a Xlite or Xtherm with a 1/8" foam on top. Might save some wt and get the warmth you need. That's what I do under an open tarp or inside a floorless MLD Solomid XL or DuoMid XL.

Have you tried a piece of Reflectix? It only adds R1.1 per layer, but the mylar affects radiation as well.

Paired with a Z-rest, it works well for me in single F digits on both bare ground and snow. The price is right, and I've used the rest of the roll on the home heating projects for which it was intended. I use a full-length piece under my 3/4 length CCF.
