Boys T Shirts Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Fruit of the Loom is the best-performing boys t shirts brand in July 2026, moving 18,000 units across 5 ASINs for 69.2% of Top 10 volume. Hanes follows with 6,000 units (23.1%), ahead of Gildan on 2,000 units (7.7%).

With 3 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 $8.69 to $25.50, 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: B0BHX9P343 booked 1K units at $25.50, with ▲ 0.0% MoM change. On the growth side, B0874WGZC7 leads positive momentum with ▲ 300.0% MoM growth on 400 units, with B0DZCX83FL close behind at ▲ 233.3% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
