I knew what Supima cotton and 600 grams per square meter meant but not Zero Twist. I now guess it means the filiments were not twisted to yield a stiffer less adsorbant "bundle". The towels have only been washed twice so I can't comment on durabi;ity; but, they are very soft and adsorbant - everything I wanted!
I can't put my finger on why these towels are not very absorbent. I've washed these towels about 5 times. Maybe I need to wash them some more. They are really, really soft but they don't dry very well. Almost like they are not really made of real cotton. They are good enough but I will not be reordering these.
The towels arrived at the time scheduled and since I sent them directly to one of the people on my Christmas list, I didn't see them, but when I asked about them, he was very pleased, said it was a surprise to see towels for Christmas but something he just happened to be needing. So he was very happy to have received them and said they were very nice towels.
