any lightwieght merino works great as a baselayer(icebreaker, smartwool, stoic). quite a few people use Under armor coldgear. the a light or heavy fleece or light down jacket for really cold days.
i use a breathable shirt then a stoic heavy merino turtleneck for warm days and then throw a light fleece over that from about 30-20 deg or a heavy fleece for anything colder.
Dude, suckin at somethin' is just the first step to bein' sorta good at somethin'
