summer = mountain hardwear or patagonia pants and some generic plain underarmor tshirt
winter = heavy duty dockers pants and longsleeve underarmor shirt with wool sweater from goodwill over it.
i dont care if it looks 'cool' as long as im peak comfy. my wool sweater looks like something my grandma knit in the 70s. no girl is gonna meet you on the trail and wanna suck the balls off your dick because of your trail fashion.
