TACVASENMen's Military Lightweight Jacket Army Cargo Windbreaker Zip Front Stand Collar Cotton Jackets with Multi Pockets

One photo appears to have lighter colored thread than the jacket, and another photo appears to imply darker colored thread... which is it?

Does it have hidden poket Inside the jacket?

Is the size chart accurate? I notice these "S" dimensions are about the same as most "L" dimensions for other jackets.

Machine washable?
