From the last time we had this thread I went and ordered bamboo briefs straight from China (through e-bay). They ended up being "Liuao" brand briefs, and they work just as well at not getting funky.
They seem the same in cuts and stitching as what is currently offered, http://www.ebay.com/itm/Men-Loose-br...item4608a500ee
, but with a more toned-down look to them
If I had my choice, I'd go with wool for cooler weather, and the silk-like bamboo for summer weather.
