One of our great German friends just returned from Tanzania where he Mountain Biked and climbed Kilimanjaro. He reported that the trip required two pairs of Pearly's, one to keep his feet warm and comfortable and another to keep his water bottle from freezing! See attached photo of Pearly water bottle insulator on the top of Africa's highest mountain.
Wolfgang's quote is "As the socks will keep my feet in good condition, I will cry out loudly "It doesn´t matter, if my feet get wet: I have Possum and Merino! Yesss!" "
