What to know before buying

Listing details to confirm

Listing details are inconsistent: one dimensions field says 10L x 10W x 10H millimetres, while feature and description text gives 28cm x 50cm x 28cm. The material is also listed as both Plastic and 90% Nylon, 10% Polyester, and the details say one compartment despite descriptions of several pockets and an internal divider. Confirm the selected listing's dimensions and construction before purchase. Water-repellent wording does not establish that the bag is waterproof.

Customer feedback reports positive impressions of quality and describes the bag as roomy enough for swimming gear. That aligns with the listed 40-litre capacity and dedicated wet-kit pocket, although the conflicting dimensions mean buyers should confirm the actual size they will receive. The overall rating distribution is mostly five-star, with a smaller range of lower ratings, but ratings alone do not explain individual experiences.
