After almost 3 decades of wool-based clothing--cycling, hiking/backpacking/daily wear, from skin to outer layers--and over 2 of those focused on one brand with mostly American-made, even sustainably grown American wool--when that one brand went out of business I started looking around. So far, this company proves a high quality product can be made in the US, and not cost a small fortune to buy.
I've worn this shirt shopping on Saturdays, and under a pack in both our local parks and Grand Canyon just last week, and the comfort levels are on par with 100% Merino fabrics. And I suspect I'll find over the long haul the synthetic woven in will give the fabric greater resistance to pilling and fade, and overall longevity. I've refused to buy synthetics for a long time for a variety of environmental reasons, but from the comfort level synthetic fabrics might be tortured into behaving almost like natural fibers, but almost isn't nearly as good as needed for my criteria. Wool insulates, so it's excellent in heat and cold, and adding in a little synthetic doesn't diminish comfort but often strengthens/lengthens the use-life.
I'm (too) slowly moving in another right direction: sun protection for my arms, and before the next trip I plan to buy the long sleeve for that purpose. And both Henley and collared-styles in the future would be (a relatively) simple rounding out of the use-line for Wuru's growing fan base.
