I agree Woubeir, will be interesting to see if there is a difference.
To sort of add to my others posts about blends–i also like the Dri Release Wool blends that i have (1 top, 1 bottom), but these only use about 11 to 12% wool to rest polyester and often a little spandex. Most of the odor control is not happening through the wool though, but from the oleo-phobic coating that they put on the synthetic fibers, which are "wrapped" with some of the Merino.
I guess the idea of the 11% or so Merino is to increase initial moisture absorption some and then have the polyester move it to the outside of the fabric. It's not a "spreading" though that happens with well wicking synthetics or say linen. While it might not dry quite as fast as a well wicking/moisture spreading 100% synthetic, i wonder if it's a bit warmer because it's wicking in a different way? If the surface area of moisture is not as increased, then less efficient evaporation and thus cooling will happen?
It's hard to say, but it may be that the wool does add a little to the odor reducing properties a bit, because on one trip, i wore the Merino Dri Release version top and my wife the cotton Dri Release version top, and the cotton one seemed to smell a bit more (though that may be accounted for in other ways too).
