Be sure to initially wash all identical towels of the same type/color four to five times separately before washing all your towels together to prevent pigment bleed.
I've tried cheap microfiber towels over the years and never really cared for them. But microfiber technology has come a long way. The towels listed above are the single best purchase I've made in a long time.
