Thanks for the info Drew. That 8% nylon should help, a little. I've noticed that a percentage of wool sweaters will often have between 10 to 20% nylon, but they are already much tougher to begin with, especially if you deliberately and carefully felt them (felted wool is so much more durable than non felted).
Here's another thing i don't quite get. Why these companies don't do higher nylon ratio blends. First off, nylon is a good fiber to mix the merino with because it's the least innately stinky of the synthetics, it's the lightest, and the strongest. Granted it's also the least thermally efficient/most conductive but most people don't rely on baselayers for serious warmth so much anyways. A 60% Merino and 40% nylon supplex or microfiber blend, even if thinner will be significantly durable, lighter, warm enough, odor resistant, should be cheaper, etc. If you wanted to keep the full odor resistance, but increase strength and durability some still, you could mix the merino with some linen--hey, it ain't kosher (in the literal sense) but i don't care.
I suspect most companies and manufacturers involved don't want to make significantly durable merino baselayers because merino is such a golden cash cow, and oh so replaceable as is.
Maybe we should sign a petition and contact a reputable company, and tell them "We want durable, odor resistant baselayers at a better price, just add 30 to 40% nylon or linen" Perhaps someone more clever than myself can come up with a catchy, rhyming chant and we can picket even.
A rough draft: "You will sell, if i don't smell, but it's gotta be light, cheap, and last more than a night!"
Now, everyone chant in unison. We CAN get'er done, change is in the air, can't you smell it (oh, wait, that's my polypro, nevermind) :)
