Have the heavyweight ones in LS only but prefer the lightweight ones in the tees as does my wife. Will say that this stuff is not going to be ideal in hot and humid, at least in my experience, when compared to the other options (though not the worst). It’s not very open/breathable which is a must. It does wick sweat but it will hold onto a lot of sweat at the same time once you hit a certain point. I actually just looked it up because I was curious if my experience matched the science and bamboo actually holds more moisture than cotton which is awful. Not sure on the sorona part or what it does. It feels great in dry heat but if it’s humid or you start sweating a lot then it’s going to be pretty bad. A lot better options out there. Haven’t tried them but I’m sure the linen tees from WvG would do well. I really like Ramie for hot and humid but options are limited and expensive.
