About this design
The real gas law on the back: pV = znRT. The z-factor is the part the textbook ideal gas law leaves out, and the reason gas is never quite as simple as it looks. For engineers who have fought a compressibility chart. Printed in light ink for dark garments. Original design, no company names or logos.
True to size. Order the size you normally wear; the size guide below shows the flat measurements.
