What to know before buying

Listing details to confirm

Water protection is unclear: the title and feature text describe water-repellent fabric and a water-repellent base, while the details list “Not Water Resistant” and “Water Resistant”. Dimensions also conflict: the details say 36L x 36W centimetres, while the feature listing gives H50 x W36 x D27 cm. Confirm the selected listing's dimensions and included wet-clothing bag before buying. These are listing inconsistencies, not proof of a product defect.

Customer feedback highlights the roomy size, pocket organisation, design and durability, with some customers reporting that it fits their swim gear and remains in use after two seasons. For buyers needing space for pool kit, this aligns with the listed 45-litre capacity and multiple pockets. Feedback on build quality is mixed, so those positive reports do not establish uniform durability.

Positive themes

  • Customers describe the backpack as roomy and say it fits their needs.
  • Customers praise its pockets, design and durability.

Mixed feedback

  • Build quality receives mixed customer feedback.

Frequently asked questions

Does it include a separate wet-clothing bag?

The title and feature text claim a separate bag for wet clothing, but the included-components field says “No components”. Check the selected listing's package contents.

How much can it hold?

The listed capacity is 45 litres. The feature text describes it as a large sports, school and leisure backpack.
