Our BIGGEST and BADDEST drying towel to date! The 1500 Drying Towel was created for heavy duty drying applications in automotive, commercial trucking, and recreational vehicles.The 1500 drying towel boasts a massive 1500 GSM density with a premium 70/30 blend twist loop design. During our testing, the 1500 could dry MULTIPLE full-size trucks with just a single towel. We found the 1500 was also ideal for boat drying and for use in commercial trucking applications. In comparison to our famous Gauntlet Drying Towel and Liquid8r Drying Towel, the 1500 offers an even more robust drying experience.
