    Smile The new Thermarest CCF

    Just in case you didn't know the new ridgerest with a sivler finish has an r-value of 2.8 which is pretty high for CCF
    I knoticed it while at work the other day and figured I should post it, I have not checked to see if others have such a high or higher r-value yet, I only know about the pads I sell and untill now never had any personal intrest in CCF due to being a ground dweller for so long.

    Saw these at the local Sports Authority this weekend. Wondered if they were any warmer.

    I like my ridgerest...as pads and hammocks go, it's pretty comfortable.

    The r-value is deceptive, however. Dave Womble wrote an excellent article on this. To summarize, a significant part of the r-value claimed for the rr is dependent on trapped air between the ridges and the ground. In a hammock, that is absent, and the r-value is degraded. Comparing apples to apples, the foam on a rr is nowhere close to 5/8", so, in effect, we're left with a 1/4" ccf pad.

    Having said all of that, it's still my favorite pad.

    I disagree with that idea-- there is still air trapped in the ridges by the hammock surface. I do wonder how much is actually added by the silver coating. They do make a large 25"x77" size that should be interesting to hammock users.

    I would have to cut darts into that. Huh. At least round the ends.

    I think Youngblood's theory is sound, but when I skimmed the report I didn't see any test results. If someone had a couple of Ridgerests they could do a simple test to determine what was warmest...

    Fill three 5 gallon buckets with warm water, ensuring they are the same temperature.

    Wrap one with a standard blue CCF, another with a Ridgerest, and a third with a Ridgerest and 1.1 nylon (or insultex).

    Take the temperature of each after a while to determine which is the warmest. That is your warmest pad, but not necessarily the best warmth/weight ratio.
