Why you should trust this review
We are frequent travelers who have brought coolers on domestic and international trips. We tested the YETI Hopper Flip 18 and alternatives across airport environments, hotel stays, and vacation destinations including beach trips and mountain hiking locations where maintaining cold food matters.
How we tested travel coolers
We packed each cooler with a full day’s worth of travel food: lunch items, snacks, and drinks with gel ice packs. We brought each through airport security, stowed in overhead bins on domestic flights, navigated hotel check-in, and used at beach and outdoor destinations. We measured food temperature throughout and evaluated practical usability at each stage of travel.
Who should buy a travel cooler?
Frequent travelers who want to eat their own food rather than airport and hotel options. Families traveling with children who need reliable snacks and drinks. Health-conscious travelers who maintain specific diets that require fresh food access during travel.
YETI Hopper Flip 18: the best travel cooler
The Flip 18 handles travel better than any other soft cooler we tested. The DryHide exterior survived being stored beneath seats, stuffed into overhead bins, and set on hotel bathroom floors without showing wear. The magnetic HydroLok zipper does not accidentally open during jostling through airport crowds. Ice packs kept food cold through a five-hour flight.
The 18-can capacity fits a full day of travel food comfortably. On hotel stays, we used it as a supplemental refrigerator on the desk, keeping perishables that the hotel mini-bar could not accommodate cold overnight.
Hydro Flask Insulated 20L Cooler: budget travel option
At $69, the Hydro Flask 20L is significantly more affordable with decent insulation performance. The roll-top closure is waterproof and secure. Ice retention is shorter — about four hours — compared to the YETI’s five to six hours. For domestic travel where you have some flexibility in food timing, this is the value choice.
What to look for in a travel cooler
Carry-on compatible dimensions: Verify your cooler fits within your airline’s carry-on size limits. Soft coolers generally compress to fit where hard coolers cannot.
Security-friendly: TSA requires ice packs to be frozen solid at screening. Liquid gel packs can be confiscated. Use hard frozen packs at departure.
Waterproof material: Travel exposes coolers to rain, wet hotel floors, and airport bathroom splashes. Waterproof exterior materials protect the cooler and contents.
Weight: Carry-on weight limits matter. A soft cooler at 3 to 4 pounds empty leaves meaningful weight allowance for food and ice packs.
Versatility: The best travel coolers also serve as beach bags, day-trip coolers, and hotel room supplemental refrigerators. Flexible multi-use designs give you more value from a single purchase.
Frequently asked questions
Can I take a cooler on a plane?+
Yes. Soft coolers generally pass TSA screening as carry-on or personal items. Hard coolers may be checked baggage. Ice packs in gel form are allowed if frozen solid at screening.
What is the best cooler for hotel room use on vacation?+
A compact soft cooler that fits in the hotel mini-fridge shelf or can be stored under the desk. The YETI Flip 18 and similar 18 to 20-can soft coolers are ideally sized.
Can I use dry ice in a travel cooler?+
Dry ice is permitted on planes in limited quantities (5.5 lbs) but requires ventilation. Most travel cooler use cases are better served by reusable gel ice packs.
How do I keep food cold during a long flight?+
Pack with frozen gel ice packs before the flight. A well-insulated soft cooler keeps food cold through most domestic flights. For flights over six hours, supplement with ice purchased after security.
