1st Model (2008?) - pretty much the same cut as the Woodland (Soviet influenced), but in ripstop. Apparently no factory velcro backings for arm pockets.
2nd Model (2009) - smooth cotton/poly fabric, 2 vertical chest zippered pockets, exposed button lower pockets, two vertical zip arm pockets. Velcro backing on arms limited, if any. Sometimes a block of velcro seen above right arm pocket.
3rd Model (2010-today) - same as above but with hidden buttons on lower pockets. Velcro backing factory made on both arm pockets, though at first it appears to have been only on the right arm pocket.
I suspect there might be 3 versions of the Digital Temperate uniform as well. However, for sure I know there is:
1st Model (2007) - pretty much same as 1st Model Digital Desert, but made from cotton cloth. No arm velcro backings on arms.
2nd Model ?? - I have not seen pictures of this, but I guess it exists and is identical to 2nd Model Digital Desert, but with cotton cloth.
3rd Model (2010- today) - same as 3rd Model Digital Desert, but in cotton cloth.
For those of you with examples and pictures... what do you say?
