Buff Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

AhaTopia is the best-performing buff brand in July 2026, moving 28,000 units across 3 ASINs for 54.9% of Top 10 volume. Geyoga follows with 7,000 units (13.7%), ahead of Fuinloth on 5,000 units (9.8%).

With 8 brands splitting the Top 10 and 78.4% 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 $6.66 to $11.99, 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: B0869LCWYG booked 1K units at $13.99, with ▲ 0.0% MoM change. On the growth side, B07GQWPVW2 leads positive momentum with ▲ 500.0% MoM growth on 300 units, with B07WCSX2LJ close behind at ▲ 300.0% MoM on 400 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
