Upairy Training Pants Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Pampers is the best-performing upairy training pants brand in July 2026, moving 10,000 units across 1 ASIN for 52.9% of Top 10 volume. MooMoo Baby follows with 3,000 units (15.9%), ahead of Hanes on 1,600 units (8.5%).

With 8 brands splitting the Top 10 and 77.2% 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 $12.09 to $49.27, 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, 2 ASINs forced its way in: B077FFNK5T booked 700 units at $16.73, with ▲ 40.0% MoM change. On the growth side, B0FT6T1JX9 leads positive momentum with ▲ 200.0% MoM growth 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
