Sun Bum Cool Down Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Sun Bum is the best-performing sun bum cool down brand in July 2026, moving 100,000 units across 7 ASINs for 62.5% of Top 10 volume. Hawaiian Tropic follows with 30,000 units (18.8%), ahead of Fruit of the Earth on 20,000 units (12.5%).

With 4 brands splitting the Top 10 and 93.8% 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 $4.28 to $13.91, 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: B087HDXS2T booked 10K units at $28.00, with ▲ 0.0% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
