I keep a Kamee sport blanket in my car for those impromptu picnics or any venue where you need a blanket. It doubles as a tablecloth as well, with ties on the corners to anchor it down.
Made of nylon, the Kamee is lightweight and water-repellent. Its ample size (90” x 60”) is big enough for the family to sit on, or to hold two beach towels side by side. Use it to cover your car seats to keep them clean when transporting your pets.
Available on the website and Amazon, the Kamee is on sale for $24.99.
