The Propper APECS Gore-Tex parka and pant are the real deal.  Official issue with NSN numbers and built to air force specifications, you can't get any more authentic.

You may be thinking that the APECS system is just ECWCS in ABU, but you'd be wrong.  This system has a totally different layout and design.

Both the parka and pant feature NIR or near infrared signature management technology that keeps your profile low at night.
