Thermal Bag PROMIS TL30, 30 L Cooler Bag, Polyester, Zipper Closure, Handles

PROMIS TL30 is a 30 L thermal bag designed as a portable cooler for beach, picnic and travel use. Constructed from polyester with a zipper closure and carrying handles, the bag provides short-term insulation for food and beverages while remaining lightweight and easy to carry. The multicolour exterior and simple shape suit everyday outdoor refrigeration and meal transport needs.

Advantages

The polyester shell resists light dirt and dries quickly, while the insulated interior reduces temperature transfer to maintain chilled items for several hours. Zipper closure secures contents and helps preserve internal temperature. Handles enable comfortable hand carrying and quick transport between locations. The 30 L capacity accommodates multiple food containers, bottles and snacks without being bulky.

Suitable for

• Beach trips and seaside picnics
• Day trips and outdoor excursions
• Park or backyard picnics
• Short grocery transports of chilled items
• Office lunches and meal delivery

How to use

Open the zipper and place cooled or pre-chilled items into the insulated compartment, distributing weight evenly to maintain balance. Close the zipper fully to reduce heat exchange. For best cooling retention, use pre-chilled containers or add ice packs wrapped in a protective pouch to avoid direct contact with food. Carry the bag by the handles and avoid leaving it in direct sunlight for prolonged periods.

Usage recommendations

For optimal performance, pre-cool the bag by placing a cold pack inside for 10–15 minutes before loading, and keep frequently used items near the top to minimize the time the bag is open. Clean the interior with a mild detergent and a damp cloth after use and allow to air dry before storage.
