SoffeMen's 3 Pack 4.1 Oz Cotton Military Tee

Is this tan shirt (not sand colored) compliant with air force ocp color (coyote brown)?

Are these compliant with the new multicam Aircrew uniforms?

Are these shirts cut long, like my old Army browns (below butt) Do they shrink to hip line after wash? (will they stay tucked in after long term use)

How close are the green ones to Army's new coyote brown?
