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