I use it as underwear summer and winter. I recommend it to everybody, but they consider this netting a bit funny.
I do not know the quality yet. Of the last shipment from Norway about 7 years ago, the quality was not as good as before.

Undershirt. Wear it all the time even under a T-shirt. Keeps cool in summer and warm in winter.
