## Customer feedback

Customer feedback highlights appearance, swimming performance and drying time as positives, alongside mixed views on sizing and how long the trunks last. Reports that the drawstring comes out easily are a practical concern for a design that relies on a drawstring waist. The generally positive overall rating distribution is encouraging, but it does not resolve those fit and durability differences.

- Mixed feedback: Sizing feedback varies, with reports of both true-to-size fit and trunks running small.
