Point 6 are some of the better ones for durability, I think. Longer lasting than Smartwool, Icebreaker or REI's merino socks in the same weight. egilbe said they make the LL Bean branded ones, and I know that they also make First Ascent socks for Eddie Bauer(exact same as the regular Point 6, just with the FA logo).
I use the midweight crews for work, plus have half a dozen pair each of the lightweight version and shorter midweight minis, but my feet vote Smartwool PhDs over anything else for hiking.
