Good fit. What I noticed is that after a few washes, a large "shadow" appeared on the chest (as if the shirt is slightly sweaty)

Very good quality and very soft. Tight fit (due to elastane), so if you want it to be more comfortable, choose a larger size.

After trying bamboo underwear from the same company - which I was extremely satisfied with - I gave their bamboo t-shirts a chance. They turned out to be exceptional, clearly softer and more elastic than regular cotton ones with a regular-to-slim fit. The only thing I cannot know at this moment is their durability over time.
