I've been looking at a number of sources for merino base layers and socks. Having little experience with merino, I was wondering if you're better off with pure, 100% merino, or a blend of merino and synthetic. I've seen a wide range of blends, from 100% merino to these trail socks from Minus33 that are 57% Merino Wool, 29% Nylon, 11% Stretch Nylon, 3% Spandex. It seems to me that a bit of synthetic would add some toughness to the merino and perhaps help prevent stretching, sagging, and so on, but it also seems as if that would perhaps reduce the odor fighting effectiveness. I'd love to hear from those with a lot of merino experience as to what they feel is the appropriate blend, or if 100% merino is better. Also, would you stick with the same blend for both socks and base layers? Finally, through a friend, I can get a deal on Icebreaker and Minus33 products... any opinion which of those two is superior? Thanks!
