Swim Shirts For Men Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Boladeci is the best-performing swim shirts for men brand in July 2026, moving 5,000 units across 2 ASINs for 23.8% of Top 10 volume. Dalavch follows with 3,000 units (14.3%), ahead of LalaHooK on 3,000 units (14.3%).

Volume is spread across 7 brands, with the top three holding 52.4% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $11.49 to $19.88, 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: B072BMXDRC booked 1K units at $14.24, with ▲ 11.1% MoM change. On the growth side, B0G64XNYLQ leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B07PLHM2LY close behind at ▲ 150.0% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
