I bowhunt out of an Eastman. Don't want to shell out the cash for a DB and it works just fine. I only bowhunt out of it on public land hunts, most of my hunting is done on private land out of trees. The one I have has shoot through mesh windows so there is no zipping and unzipping other than when you first put it out. Just make sure if you use this to have fixed blade broadheads. Never tried to shoot a mech. through the window, but I'd hate for it to make the blades deploy and mess up a shot at a deer.
