As an expert in the field, I present the Weekender Insulated Cooler Bag. With a 12L capacity, 27x22x28cm dimensions, and premium leak-proof insulated lining, this bag keeps food and drinks hot or cold. It also boasts a hard-shell sturdy base, mesh side pockets, and a comfortable shoulder strap. Plus, it's free of harmful chemicals like BPA and Phthalate.

Cleaning and care tips:

• Use mild dish soap and a damp sponge to wipe both the interior and exterior fabrics. Do not use chlorine bleach. Allow to air dry.
  
• Do not place warm or hot dishes directly from the oven into the bag to prevent damage to the insulated lining.
  
• Do not place the bag in an oven, microwave, washing machine, dryer or dishwasher.
