The Deluxe Blind uses a revolutionary "patented" scent-proof design which allows you to hunt on the ground or elevated without the worry of being smelled, seen or heard. The air-tight Deluxe Blind pulls in fresh air through intake ports located near the base of the blind and drafts air up and out of an exhaust pipe over 30 feet high---working much like the chimney in your home! The Deluxe Blind comes with a deluxe-gasketed, locking, full-size walk-in door for use on the ground or a trap-door-through-the-floor when used elevated. Tinted polycarbonate windows allow a 360° view while providing concealment for the hunter. The eye-level windows seal against a gasket to keep them scent tight and weatherproof, and flip up and out of the way when open. This blind has a through-bolt design with interlocking corners. It is lightweight and virtually maintenance-free, weather and bug resistant. It has a heavy-duty polyethylene olive drab exterior with black interior, and a carpeted, 3/4" pressure-treated plywood floor. 22 Square feet. Capacity: 500 lbs. Door Dimensions: 35" W x 55" H.
