Mens Thongs Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

FITORY is the best-performing mens thongs brand in July 2026, moving 2,000 units across 2 ASINs for 23.5% of Top 10 volume. REEF follows with 2,000 units (23.5%), ahead of KuaiLu on 1,500 units (17.6%).

With 6 brands splitting the Top 10 and 64.7% 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 $13.99 to $42.88, 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: B000KS6SMG booked 700 units at $46.26, with ▲ 250.0% MoM change. On the growth side, B0GT2HDKHX leads positive momentum with ▲ 300.0% MoM growth on 400 units, with B0CNX5DRNV close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
