Best Size 6 Diapers Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Pampers is the best-performing size 6 diapers brand in July 2026, moving 46,000 units across 5 ASINs for 54.8% of Top 10 volume. HUGGIES follows with 22,000 units (26.2%), ahead of GoodNites on 10,000 units (11.9%).
With 4 brands splitting the Top 10 and 92.9% 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 $29.99 to $41.24, which frames the price band a competing listing has to justify.

Trending Size 6 Diapers Products — Growth Leaders & New Top 10 Entrants
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: B08SW9LVZD booked 6K units at $50.74, with ▲ 20.0% MoM change. On the growth side, B0GQSKB2ZJ leads positive momentum with ▲ 1100.0% MoM growth on 600 units, with B00R4HZ3A4 close behind at ▲ 100.0% MoM on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
