So for awhile now, i've been wanting to find a Merino baselayer (top or bottom) that has a slight Merino ratio predominance over rest being nylon.
More specifically, something like 60/55% Merino to 40/45% nylon. Reasoning being a combo of factors. Nylon is the least stinky of the synthetics, the lightest of the commonly used ones except polypro, and the strongest and most durable of the commonly used. So, theoretically speaking, something with that ratio of Merino wool to rest nylon, should be fairly durable and fairly odor resistant.
Some Darn Tough socks that i have, bears this out very well. One pair is like 55% merino to 40% nylon and rest spandex, and it has great odor control, and course a sock is going to much more tested in this area than one's shirt or pants. The little odor it does accrue, washes out easily.
Anyways here is a link:

The baselayers i'm talking about are the Redington Redilayer brand, both the tops and bottoms use a ratio/blend of 55% Merino to 45% nylon. Ordered a pair of the bottoms and with my 30% coupon, got them for like 20 dollars.
If the Merino happens to be good quality and more comfortable on the skin and the garment otherwise well constructed, this is an amazing product and deal and theoretically speaking should be MUCH more durable than the 100% merino wool baselayers.
