Here is a quote about this blind I found:

Quote "The 8 window configuration is a bowhunter’s dream. The windows are not small portals but large trapezoid/triangle shoot-through mesh windows all the way around the blind that allow the bowhunter to follow the game without obstruction. All 8 window mesh panels are fully removal (Velcro) for those that don’t like or can’t shoot through mesh and are all replacable The one feature of the window system that is a winner is the hook and loop/zipper panels (non-velcro) Let’s say you have a turkey that works in from behind your blind, shooting lane, and decoy set-up and hangs up at around 20-30 yards. With other blinds, you would have to drop one whole side of the blind to prevent skylighting and then in hopes of not creating any movement with a wary Tom at that distance open the other side for a possible shot. With the ASAT window configuration, all I would have to do is hook the shooting lane window closed to prevent skylighting from behind and drop the window where the bird is at with minimal movement. Yes, I have tried with another blind set-up and the ASAT blind system is much faster, quieter, and stealthier!" end of quote

This is a quote from a guy selling them and not me. I wanted to clarify this. I have not seen more than you have from these pics.
