Streak free and quick drying. Big and pricy but worth it.
Size: 1 Pack (24" x 36")
Great for drying off your car especially in places where the water pools. Streak free and covers a lot of area. It’s big and versatile- it would work as a pet drying towel too. Soft and good quality. Great gift for a car buff. Not cheap but man does it cut down on drying time.

Great size, super soft, and extremely efficient.
Size: 1 Pack (24" x 36")
Love this drying towel. It’s super soft, super efficient and cuts my dry time in half. The size is perfect for my car as it covers most of my roof making it really easy and quick to dry the whole car. It’s also super absorbent and definitely worth every penny.
