Mens Shirts Short Sleeve Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

COOFANDY is the best-performing mens shirts short sleeve brand in July 2026, moving 8,000 units across 2 ASINs for 22.9% of Top 10 volume. Hanes follows with 7,000 units (20.0%), ahead of MCPORO on 6,000 units (17.1%).

With 8 brands splitting the Top 10 and 60.0% 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 $18.77 to $23.60, 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, 2 ASINs forced its way in: B0BV27DL6Y booked 3K units at $23.97. On the growth side, B0C12BLCDL leads positive momentum with ▲ 50.0% MoM growth on 600 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
