Cotton Shirt Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Hanes is the best-performing cotton shirt brand in July 2026, moving 32,000 units across 5 ASINs for 57.1% of Top 10 volume. Gildan follows with 15,000 units (26.8%), ahead of COOFANDY on 5,000 units (8.9%).

With 4 brands splitting the Top 10 and 92.9% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $18.68 to $23.24, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0DJNJBVWG booked 4K units at $9.99, with ▲ 0.0% MoM change. On the growth side, B01DSQQ5Q0 leads positive momentum with ▲ 133.3% MoM growth on 700 units, with B01DDFXIK2 close behind at ▲ 125.0% MoM on 900 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
