These are just like the old ON perfect tanks!! I've looked everywhere for some more ON perfect tanks because I loved them and nothing has matched them until now. For everyone who is missing them, these are it! Don't be confused because there are ones labeled "favorite" tanks that are not it either. ...The label matches exactly- 58% Cotton, 38% Polyester, 4% Spandex. The length is a tad shorter than before but it's almost the same long length I love. That could just be the inconsistencies that sometimes occur in the sizing. I wear them every day for layering under all my tops and they've held up for years. I've desperately needed to replace them and tried everywhere and finally found them so I've stocked up!
