Seven-hole cotton belongs to a special superfine polyester chemical fiber material, and its fiber section has seven cavities, so it is called seven-hole cotton. Although seven-hole cotton is not cotton in the traditional sense, it just looks like cotton in appearance. The more fiber cavities there are, the better its breathability, warmth retention and bulkiness will be. Because it is stored in the cavities, it looks softer.
