No - you would be fine with that bivy. It is just a mesh insert that he is refering to and removable. The perimeter mesh could be an issue on any shelter, however.

Side note: On my MLD SoloMid, I have perimeter bug netting but no velcro. Combination of zipper for the door and snaps for the velcro. Works well. The upper vent has a velcro bug insert and there has not been any issue with neeting geting stuck in the velcro because of the size.
