This pieces are sharp and crisp and they are made out of the thick Tyvek,
a fabric that resembles paper in its lightest form yet still remains comfortable to wear.
The tailored button down is slim fitted with a small collar. It is very light with a single layer of thin & breathing Tyvek.
A high performance, water resistant, breathable, washable fabric.
The brand is called UEG (USA E GETTA) and you can get the pieces here.
I don't think that it's suuper comfi, but it looks fun and the typography is really nice.
