Depends on the location.
I'm a firm believer of having a screen BEHIND me, if possible, sitting or standing in front of it.
With complimentary camo, I can move without breaking my profile.
Never have seen the need for a closed in enclosure...
I quickly learned that being behind a blind/screen, just doean't work.
Deer (or other game) react to any change in profiles, as you move to shoot.
