So I was in REI earlier this week to start replacing my base layers. As I was checking out, the cashier asked if I had seen the new Odlo line. Apparently REI is the only N Am distributor. The Ceramicool/ Ceramiwool lines actually use finely ground and re-kilned ceramic tiles embedded in the fibers.

Anyone try them yet?
