In reply to Muel:
Bridgedale socks are the best in my opinion and I'm rather OCD about socks. My entire sock drawer is now entirely bridgedale :-P
My favourie for regular every day are either Trekker or Trail if it's really hot. When it's cold or I have my heavier boots on it's Summit socks all the way. I don't usually wear liner socks unless it's for warmth (i.e Norway, etc). The summit socks are the only thick socks I like, the trekker socks I ocassionally try other brands instead of but like I say I'm very fussy and I've not found any that I prefer yet.
I bought loads at once from amazon, they were quite a bit cheaper and signing up the clothing newslatter saved me an additional 25%. I like the woolfusion socks over the other varieties of bridgedale socks.
While we're on the topic of under garments, can anyone recommend any base layer boxers? I have about 10 different types and 9 of them are rubbish. they 10th kind i have a few pairs of but they're now discontined (lowe alpine dryflo brief). Most of the ones I've tried the material is very thin and rides up and most dont have enough 'leg' to keep the boys in the barracks... as it were.
