The new Microfiber Chamois is fast becoming the drying option of choice because of performance, durability, and value. Unlike other synthetic chamois, the Microfiber Chamois is 100% polyamide. Polyamide is the drying and absorbing material present in microfiber towels, either 20% or 30%, as combined with 80% or 70% polyester. This material stays more flexible even when dry. Also the Microfiber Chamois requires no "breaking in." It is highly absorbent, easy to work with, and dries without streaks or water tracks. Machine washable.
