Had the shirt (white) in Corsica for trekking with a heavy rucksack on. Av. Temp 26 degrees. The sweat is optimally transported. You always feel good on the skin and does not feel sweaty. Furthermore, I would go so far as to even claim that it even has cooling. Technically smell after three days in the sun even at this material time closing what lies in the nature of things.
Fit: I wear normally L (185cm approximately 83 kg Athletic)
But ordered due to the recessions M, so a number of small and it fits perfectly. Should it hot is not skin tight, but schlappert nowhere.
In US - pages there are often the question whether one would recommend this to a friend ...
