Window AC Cover Inside with Wind-Proof Wing - Silver Thickened for Winter M

[UNIQUE GAP WIND-PROOF WING DESIGN] Unlike ordinary inside ac covers for winter, our cover features extended side wings to seal the gaps between your window frame and AC unit. This winter anti-cold ac cover blocks icy drafts leaking through installation cracks, ensuring 360 protection and keeping your room cozy. | [SILVER COATED HEAT REFLECTIVE] The surface of this window air conditioner cover indoor is made of silver-coated Oxford fabric that reflects indoor thermal radiation back into the room. This radiant barrier prevents heat loss and improves energy efficiency, making it a must-have air conditioner cover indoor solution for harsh winters. | [EXTRA-THICK DOUBLE INSULATION] Engineered with thickened double-layer cotton padding sandwiched between reinforced Oxford cloth, this window ac unit cover offers superior warmth compared to thin covers. The heavy-duty build effectively blocks cold air penetration while remaining durable for multi-season use. | [WINDPROOF & WATERPROOF DEFENSE] Crafted from upgraded thickened Oxford fabric, this cover features a dual-layer build with an internal waterproof membrane and padded cotton. It effectively blocks cold air infiltration from outside while preventing heat loss, significantly extending your AC unit's lifespan during the off-season. | [ECO VACUUM PACKAGING NOTE] Shipped in a reusable vacuum bag for better environmental protection and transport safety. Note: The cover may appear flat or wrinkled upon arrival. Simply give it a gentle pat and let it sit, and it will slowly naturally expand to its full, plump, "bread-like" thickness and softness. Available in M-XL (43-63cm width) to fit most units.
