Our tester left a cooler containing the ice pack in a car on an 80-degree day and was pleased that it performed as advertised: A bottle of apple cider and fresh vegetables stayed cold for four hours and remained in great condition for about seven hours.

Though the ice packs are on the pricier side, they come in three sizes (1-, 2-, and 4-pound), making them an excellent choice for both small and large coolers. Items in checked luggage usually stay colder than those taken on board, but to a great extent it depends on what you plan to take and how long you'll travel. Shut It – Try to minimise the amount of time your cooler is open and also put chilled items back as soon as you’re finished with them.

The wide, main zippered compartment has no organizational features, but it’s easy to load — we fit 40 cans sans ice and 14 cans with the one-third-to-two-thirds cans-to-ice ratio — and the buckle-down rolltop felt secure when filled at varying capacities. Hard structure: the combination of foam and corrugated plastic gives the bag a sturdy, hard structure.

The ripstop material stood up well to our durability and leak tests, and temperature retention was notable. If you add ice blocks straight from the freezer, they’ll help keep things at their best for even longer. The top-loading design makes it a cinch to load, unload, and peek into the bag to suss out available room.Growing technology has made it easier to keep drinks and foods cold and fresh with various promotional items like thermoses, insulated mugs, lunch bags, and thermos.

Soft packs will stay cold for several hours, whereas hard ice packs often keep their chilling power for 10 or more hours.

Very handy bags I keep 3 in the car 3 in house , keep foods cold added to cool boxes then to put food's in fridge/ freezer.A few cool blocks will keep picnic food cold for the day, however, if you want to have ice for your drinks then we recommend using double the amount of ice compared to the contents.
