DickiesMen's 13"MLTI PKT W/SRT Short

Why are these shorts advertised as 'Relaxed Fit' on the main picture, then reading the small print further down the page they say they are 'Loose Fit'

Can you advise on the accuracy of the sizing? Would a 34" waist be as described?

is sz34 waist 34 inches?

What's the difference between 40W 40 and SZ40?
