Karina is zipped into a full-body, heavy rubber sleepsack. Her arms are held in internal sleeves and her feet are also held in sleeves that prevent movement.
A heavy rubber hood is zipped over her hood. It has a 'snout' that moves in and out, making breathing difficult. The gag means that Karina must breathe through her nose. The hood has a lockable collar, but Karina needs her hands to free herself.
Watch what happens when her only supply of air is cut off by a finger placed over the snout!
