IF you have a large enough blind like my main one, gun ports. Clear Lexan held in place by rare earth magnets and rotating spring arms, fully removable to keep open after the blind is toasty and your coat is off. The rest of the windows are Lexan with camouflage paint applied to certain outside areas established pre placement. You can move around with the deer not seeing you and the predawn glow of the heater is not noticable on the outside. Any sound from the inside of the blind does not really go outside the blind i.e. pop the top!
