A simple dark terry towel.
Allow 3-5 extra days. We bring these in from neighbouring wholesaler.
Feedback from our first customer/tester. "Not the quality of the white towels. Thinner and not as luxurious. First wash produced a lot of lint, but settled down for subsequent washes. There were loose threads. The navy is nice and coordinates well with your cabana towel."
Further ... customers have reported loose strings. Definitely an ECONO grade.
