A flexible and reusable plastic window covering is designed to be selectively attached over an existing window opening to reduce or eliminate air leakage and drafts. Either hook and loop fasteners or locking strips can be used to attach the plastic sheath over a window opening and, if desired, the sheath can be provided with a zipper to allow air flow through the window. Special locking strips can be used to securely attach the flexible sheath over a window opening while facilitating an easy removal when required.
