Kona Ice Pack for Coolers – 4 lb Reusable Refreezable Cooler Ice Pack, Long Lasting Gel Pack for Camping, Travel, Lunch, Beach, Colder Than Ice -5°C

I was looking for something to pre-chill and maintain ice in a rotomolded cooler. The major brands were expensive and smaller. The Kona Large Ice Packs are perfect. At 4pounds total and gel filled, they freeze quickly and once truly frozen, they stay very cold for days in a cooler. They arrive empty except for the powder in the bottom. You add the called for amount of water, shake, and presto! I added the called for amount of water, carefully measured, and none of my packs swelled. I liked this product enough that I purchased another 4, so now have 8 total. the Kona Large Ice Packs are well built, thick plastic, and the handle is super...handy. If you're looking for a large ice pack to extend the ice in a cooler, these are really terrific.

I bought these (2), and I am so happy I did. I’ve pre-cooled ice chests for drinks. We have used them endlessly in cold bags for when we go grocery shopping and for frequent short or long trips! Here in Texas it’s pretty much warm to hot year round and you need to get your milk and cold stuff home PDQ! I highly recommend these and definitely the instructions for mixing the product and water you add is very good! They WORK!

I was a bit skeptical when they showed up. After adding water, and freezing them I felt better. On a recent camping trip they stayed frozen for two days in a yeti. Kept things cold for four days.

Nice size and dimensions, and seemed solid, but 3 of the 4 that came in set leaked after filling and tightening screw-on childproof cap - every time ice pack was laid on its side where liquid filling reached the screw-on cap, it had a slow leak...tried numerous times to tighten to eliminate the leak all to no avail....ended up tossing them all, a waste of money...

These are great for long game days! No leaks and reusable. Stays cold for long and keeps drinks cool. Easy to freeze!

Works great

These ice packs are great! It may seem a bit unusual to have to actually add water to mix the chemical inside the pack, but it is very easy. Have no fear!! These ice packs keep their cold for a very long time and ice packs avoid the watery mess of melting ice cubes. Keeping your cooler cold and dry with the Kona Large Ice Packs. I really like the molded in handles for both placing in the freezer to get frozen and then grabbing them to put in the cooler. Recommended!

Let’s start with the good news: these ice packs absolutely work. Once filled and frozen, they deliver impressively cold performance. In my test run, a single ice pack kept canned drinks chilled in a small cooler for 18 hours, even with moderate openings throughout the day. They also freeze efficiently, stack neatly in the freezer, and fit well in my coolers without taking up much space, but ice takes up space too. When functioning properly, they’re a solid upgrade over traditional ice (cleaner, colder, and reusable). Now for the not-so-great part. Quality control was a 50/50 experience. I bought four of these Kona packs, and two arrived with leaky caps. The caps wouldn’t seal no matter how tightly I turned them, and the first one I tried to fill immediately leaked. That’s a rough first impression, and it made me consider returning the entire set. Fortunately, I found a workaround: plumber’s tape. A quick wrap around the threads allowed the caps to seal properly, and once that was done, the leaking issue was completely resolved. Still, needing to DIY a fix on brand-new ice packs isn’t ideal. My final thoughts: Strong Value, but Quality Control Makes It a Gamble. I’m dropping two stars from my rating because only half of the packs worked correctly out of the box. That’s a significant quality control miss. But once fixed, the performance is genuinely impressive, and the economic value is strong. If you’re lucky enough to receive properly sealable Kona Ice Packs, you’ll likely be very happy with the purchase. If not, a little plumber’s tape may save the day.

These fit my cooler perfect and kept everything cold for 2 days.

works great. stays cold longer than an ice block. only downfall is the are too big to put two on the bottom of my 60l cabelas cooler so i use one of these and a 2lb one of same brand. then put some food and layer another one of these with another 2lb one. afterwords i will load the coolers remaining space with blocks. my cabelas cooler stays cold up to 10 days (verified personally). the cubed ice melts and start to turn to water after 5-7 days but these ice packs are still mostly frozen.

Great Ice Packs- they do the job. I recommend.

Works just fine, no complaints, I mean it's an ice pack

Vraiment pratique pour glacière. Garde bien les aliments et les breuvages au froid. Je recommande.
