I know the the guy who designed them. He is a hunting guide over here in Eastern Oregon. I personally have never used one, but they sound like they would be handy. Hope that helps,

I noticed they were in the "discounted/discontinued" section on Blacks Creek site. That's a shame.....it looks like a good product. I bought my first Blacks Creek product this summer.....one of the Wild Thing packs for the Double Bull blind. It is unreal the amount of thought that was put into that thing. It's awesome.
I found a place online that still had the Predator pack. I ordered one yesterday. I'll re-post a "review" once I receive it.
