eBay find: experimental PCU jacket

Another mystery for the archives, a seller posted several of these all at once but they went for far to much for me to scoop one up. They were all solid colors, various greens and tans:

The seller claimed they were Goretex instead of the DWR nylon of the normal Level 5 garment this is obviously patterned off of, but with eBay seller's tenuous grasp of fabric terms this is unconfirmed. While I think the hoodless PCU level 5 garment is a fantastic jacket (in some ways better then the new hooded version) I have mixed feelings about hoodless goretex jackets in general. I think the cut of this jacket has advantages over the ECWCS and PCU level 6 jackets, and maybe with a helmet it makes sense to ditch the hood. I wouldn't know, I only ever wear a hat.
