 FAQs 

  • HOW DO COOL BAGS WORK?

    Cool bags work by using layered thermal insulation to block heat transfer and keep cold air trapped inside.

    When combined with pre-chilled food and ice packs, the bag maintains a low internal temperature for hours.

  • HOW LONG DO COOL BAGS STAY COLD?

    On average, a standard cool bag will keep contents chilled for 4 to 8 hours. However, premium insulated cool bags - especially when used with ice packs - can keep food and drinks cold for up to 12 to 24 hours.

  • WHAT SIZE COOL BAG DO I NEED?

    • Small (3L to 9L): Best for single lunches, daily commutes, or school.
    • Medium (10L to 18L): Best for couples, solo day trips, or beach visits. 
    • Large (20L to 35L+): Best for family picnics, camping, or group outings. 
  • CAN YOU USE ICE PACKS IN A COOL BAG?

    Yes, absolutely. Ice packs (or freeze boards) are essential for getting the best performance out of your cool bag. While insulation slows down heat entry, ice packs actively lower and maintain the internal temperature.

  • COOL BAG VS COOL BOX: WHAT IS THE DIFFERENCE

    Cool Bag: Lightweight, flexible, and easy to fold away. Keeps items chilled for up to a day - ideal for day trips, picnics, and work lunches.

    Cool Box: Rigid, heavy-duty, and bulkier. Offers maximum insulation to keep items cold for multiple days - ideal for camping and long road trips.
