Best Men Swim Trunks Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
maamgic is the best-performing men swim trunks brand in July 2026, moving 6,000 units across 4 ASINs for 30.0% of Top 10 volume. FT FENTENG follows with 5,000 units (25.0%), ahead of ELETOP on 4,000 units (20.0%).
With 5 brands splitting the Top 10 and 75.0% 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 $17.99 to $24.65, which frames the price band a competing listing has to justify.

Trending Men Swim Trunks Products — Growth Leaders & New Top 10 Entrants
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: B0861QWJ18 booked 1K units at $17.93, with ▲ 0.0% MoM change. On the growth side, B0GL2114F4 leads positive momentum with ▲ 900.0% MoM growth on 500 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
