# Arena Spiky III Duffle 40, 40L

Arena Spiky III Duffle 40 is a 40-litre sports holdall with a large main compartment, a deep side pocket for wet kit or footwear, and a smaller pocket for personal items. Its water-repellent claims and breathable mesh inserts are aimed at managing damp gear, rather than making the bag waterproof.

## Before you buy

- 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.

## Less suited to

## Customer feedback

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.

- Positive themes: Customers appreciate its size and room for swimming gear.
