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

BAMBOO COOL is the best-performing birddogs mens shorts brand in July 2026, moving 2,000 units across 1 ASIN for 18.2% of Top 10 volume. JWJ follows with 2,000 units (18.2%), ahead of Amazon Essentials on 1,000 units (9.1%).

Volume is spread across 9 brands, with the top three holding 45.5% 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 $18.90 to $49.99, 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: B01JQTN8SQ booked 1K units at $18.90, with ▲ 42.9% MoM change. On the growth side, B0BQQZQYP8 leads positive momentum with ▲ 100.0% MoM growth on 200 units, with B01JQTNK7U close behind at ▲ 50.0% MoM on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
