Would those of you who have been wearing wool (as the main baselayer, as opposed to insulation under other tops, while hiking) care to comment on it? I would like to switch from nylon to wool, but wonder if the latter is as protective from the sun–not to mention durable under constant pack wear. Which of the major lightweight-wool garment manufacturers–Icebreaker, Ibex, Smartwool, Patagonia–produces the most tightly-woven, durable top?
