New old stock US Navy general purpose trunks.  These are Khaki in color and appear to be PT or swimming trunks.  From as much as I can gather the stock number for these shorts was assigned in 1960...  these particular shorts are dated 1980 but these seem to be a very scarce item to find these days.. these are all size small.  I believe these are the type of shorts you see SEALS and frogmen wearing in the 70's 80's era.. I could be wrong maybe they were wearing the UDT type shorts then..  The two divers in the picture posted don't appear to be wearing the UDT type shorts and do appear to be wearing shorts more like the ones I have for sale... if i'm off base on any of this please feel free to jump in and set me straight! Ships worldwide thanks for looking! 

The actual measurments are as follows:

waist unstretched 23 inches

waist stretched 31 inches

inseam 2.5 inches

rise from crotch to waist 12
