So far so good, very breathable and extremely quick drying. Haven't used them enough to give a long term review but will update if necessary. I like these!

Used on their own with Salomon Speed Assault 2 and Merrell Jungle Mocs during (very) warm weather. They breathe well, don’t heat up or retain moisture. No odour despite poly-blend material. Cooler than Sarma Pattern socks (but not in looks). Very comfortable.

Tried these out after giving them a wash. Two things, one they shrink easily, but stretch super well so it doesn't effect the fit. And second as a first layer for the feet, paired with the hiking merino wool socks. They keep you feet really warm, to the point i think these might work similar to a mesh base layer for clothing. But if they are your only layer, your feet breath extremely well so would be excellent on hot days. Only reason i don't think them higher rating is because I need to see how they hold up, since i am unsure how durable that mesh layer will be. But overall, I like them quiet a lot already and just wish we had a lower cut option. Additional notes: used these a few more times. And omg if using as base layer with the tst hiking socks, your feet will be warm. On a 13 degree day, used them for a 10km walk on a trail. And when i got near the end my feet felt damp, got home and took off boots. Never have my feet sweated this much, now once the hiking sock came off. I instantly felt these sock letting moisture evaporate. But that outer thick sock was wet. So this weirdly enough at great for summer by themselves, but also really good for cold winter pair with a thicker sock
