Detailed measurements of the extreme jackets
Here are the detailed measurements of the Extreme Jackets in centimeters.
Extreme Long Coat (106) is about 35 cm longer (B in the photo) than a regular Extreme Jacket.
Extreme Zipper Jacket (616) with Pockets is about 6 cm narrower (E and F in the photo) than the regular Extreme Jacket.
These measurements should give you an idea of what the jackets are like. There most likely are some errors in the sizes resulting from the way measurements are taken. Also the factory is not run by robots which also amounts to some variation.
Notice that there are these special kind of cuffs/wind locks in both hands which allow many centimeters of flexibility to the lengths. The measurements are taken from the outer fabric (not including the cuffs).
