Thanks. Unfortunately it looks like only in Medium and Large so I'm still out of luck. I'd love to see the "Okayest" shirts in another color option though it would be tough in white with the lettering of the words.
Cotton has it's downsides but there are applications where it is the best. If you stay relatively dry you can't beat it in hot weather.
My guess would be XL
Just try Nike Dri-fit. It's magical
Funny you say that. I've worn Nike Dri-Fit on multiple Dall Sheep backpacking hunts (10-14 days) and have thought they were remarkably GOOD at managing odors for not being anti-microbial. I have Sitka, KUIU Tiburon is okay, "ultra merino" is no good for me. The first lite aero wool is much better...but this one Dri-fit shirt I have is the best. I can't leave it at home. I try to, but I always go back to it.I sweat. A LOT. I'll wear Nike dri-fit to the gym (especially since my wife works there and we get the stuff cheap) but there's nothing around that i've found that starts to stink any faster than Nike dri-fit.
For hunting, I've been running either my Kuiu ultra 125 or a old, cheap merino icebreaker shit that I have and can't seem to wear out. Keep a spare dry one in the pack and a hand towel on the belt as mentioned previously for mopping the brow. Once the top is reached, ring out the shirt i've been wearing, clip it to the outside of my pack, and put on the new one.
Having heard good things about the Sitka core shirt with the purported wicking ability and stink control, I am planning on trying one of those this fall or later this summer.
When it's hot, give me thin cotton, preferably with a looser weave and some airflow.
