Black Long Sleeve Top Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

MAGCOMSEN is the best-performing black long sleeve top brand in July 2026, moving 2,000 units across 1 ASIN for 18.7% of Top 10 volume. TNNZEET follows with 2,000 units (18.7%), ahead of Trendy Queen on 1,000 units (9.3%).

Volume is spread across 9 brands, with the top three holding 46.7% 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 $6.99 to $9.98, 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: B0FDW3L8YX booked 900 units at $6.99, with ▲ 50.0% MoM change. On the growth side, B0F9NJDHQD leads positive momentum with ▲ 300.0% MoM growth on 200 units, with B0F5QGQX25 close behind at ▲ 200.0% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
