This Large 400 GSM towel is designed with a 80/20 microfiber blend. Our drying towels were made specifically for large drying tasks, able to dry your entire car by itself. Drying can be frustrating! The problem is most towels are not able to take in water quickly and efficiently store it, which is why streaks and water spots form. Our 35” x 25” Our Microfiber Drying Towel is different. With our hydrophilic loop design, it quickly takes in surrounding liquids, moves it away from the towel’s surface, & stores it in the interior, enabling you to dry larger amounts without saturating the towel.
