How to use

Open the zipper and place food and drinks inside ensuring even distribution to maintain temperature.

After use, empty contents, wipe the interior with a damp cloth and allow to air dry before storing.

Usage recommendations

For improved cooling performance, pre-cool the bag or include frozen packs. Avoid placing hot items directly against the insulation to prevent moisture buildup and clean spills promptly to maintain hygiene and material condition.
