I am lost when i see the difference between some pads claimed R value :
i calculated the R value x surface / weight of a few foam pads, and added neoair pad for the comparison.
looks like the zotefoam in 0,5mm has a density 2x the gossamer gear pads ( both are evazote ) but for the same thickness they isolate less ???
anyone understand something with that ?
seems the number i scanned arent very clear so some numbers :
zotefoam 150x50x0,5, 175g R=0,66 , density 0,047g/cm3
GG thinlight 150x50x 0,64, 114g , R= 0,9, density 0,024g/cm3
if you make the thickness ratio for the GG 0,64->0,5
GG thinlight 150x150x0,5 , 89g , R=0,70 , density = 0,024g/cm3
