Pantac had a PCU L5 ORC knock off that was on par.
The Ebairsoft/ACM PCU's tear easily.
Not saying the ORC Ind. PCU L5 had issues of wear, but a thin material like that isn't going to hold out long, especially if there are blackberry bushes/thistles around.
I've read on ASF that they tear easily and the zippers are terrible. Other than that if you want to pull off a load out, the knock offs are your only option since Pantac discontinued theirs and ORC no longer makes the PCU tops.

If you're lucky you can find them on eBay for ~250-400 dollars.
