Been wearing kuiu 210 merino hoody for 1.5 years now, probably 60+ days hunting public lands in Texas where you have to hike in the where you sit. Through mesquite, greebriar vines, etc and it doesn't have any noticeable wear. Very quiet and does what merino should do in regards to odor. Some place the fit has me wondering what they were thinking. The cuffs are pretty tight, and I have VERY thin forearms and wrists. The hood can pull your hat back if you have a ball cap on and throw the hood over it and look down, so I would like a bit more room there.
Overall I am happy with it.
Only FL piece I have is the zip aerowool top. Love the fit, love how well it dries, and for the most part odor control is good with one annoying exception. The piece has a different fabric with little vent hole all through it on the underarms. I am convinced this either has a different blend or is totally synthetic because it holds smell. It doesn't get as bad as something like the patagonia capilene 1 shirt I have, but you can sweat, it doesn't smell good, and I can leave it hanging in the sun for a day or 2 and a faint odor stays.
I will probably buy more firstlite in the future, I might buy more Kuiu, but their lack of a stated stance on public land hunting irks me.
