Cooler bag for travelling

Ohhh lepas tanggung! A few of us bring those insulated cooler bags from Decathlon or Daiso, they're compact enough for carry-on and keep things cold for a few hours, especially kalau boleh pairing with those freezer packs or even a ziploc of ice. Some mums I know swear by the soft-sided cooler bags sebab easier to pack dalam luggage and airport staff tak buat hal, plus during the flight you boleh ask for ice from the cabin crew to refresh the packs.
