Maamgic Mens Swim Trunks Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

maamgic is the best-performing maamgic mens swim trunks brand in July 2026, moving 9,900 units across 9 ASINs for 94.3% of Top 10 volume. HODOSPORTS follows with 600 units (5.7%).

With 2 brands splitting the Top 10 and 100.0% 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 $23.19 to $27.42, 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: B0BMFGYWGJ booked 800 units at $30.99, with ▼ 11.1% MoM change. On the growth side, B0DH1SL12V leads positive momentum with ▲ 100.0% MoM growth on 100 units, with B0DRN9J3DC close behind at ▲ 100.0% MoM on 100 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
