Koeltas Rivacase Gremio 5717 17 L grijs polyester

The Rivacase Gremio 5717 cooler bag is a compact insulated bag with a 17L capacity designed to keep food and drinks cool during short trips. Constructed from durable polyester in a grey finish, it combines lightweight portability with basic thermal protection. With external dimensions around 220 mm in width and height and a net weight of approximately 350 g, the bag is intended for everyday outdoor use such as picnics, commuting meals and short travels.

Advantages

The cooler bag offers a balance of light weight and sufficient storage volume for up to 17 litres, making it easy to carry while still holding multiple cans, bottles or meal containers. The polyester exterior provides abrasion resistance and simple cleaning, and the insulated interior reduces temperature exchange to preserve chilled items for a few hours. Its compact footprint and neutral grey colour make it unobtrusive and suitable for varied environments.

How to use

Prepare the cooler bag by ensuring the interior is clean and dry before use. Pre-chill contents or add ice packs to extend cooling performance, then close the main zipper to reduce temperature exchange. Distribute items evenly to avoid overfilling and to allow airflow around ice packs. After use, empty any melted water, wipe the interior and exterior surfaces with a damp cloth and allow the bag to air dry before storage.

Recommendations

For optimal short-term cooling, use reusable ice packs rather than loose ice to minimize moisture inside the bag. Keep the bag closed when not accessing contents and avoid prolonged exposure to direct sunlight to preserve insulation performance and the polyester finish.
