>>2488624where i live cold rain and intense wind for hours is most dayhikes unless its an el nino year. its like that most of the year all day, so the only way around it is to 'hunker down' and not hike for 3/4ths of the year. it is what it is.
wool, or your insulation layer in general isn't the biggest concern with staying dry. all that stuff should be staying dry unless you fucked up. your weather resistance layers matter the most.
>>2488775yes when i'm working in the cold i wear a thin shirt. undershirt might not be correct. i like either a tank top or a loose fitting thin t shirt. you need air flow on your armpits. that's key. tank tops can be a bit thicker and warmer. i wear warm gloves and layer up my legs still. if its really cold i can add a unbuttoned flannel or fleece, but i won't wear much. when i'm done breathing heavy the layers go on one by one a few minutes apart as i get cold.
if you are a chad, go with mesh
