SUNLUG Cooler Ice Packs Reusable Ice Packs for Coolers Long Lasting Freezer Packs for Cooler Bag, Lunch Bags, Cooler Backpacks

So I’m a personal shopper so I need a longer lasting ice pack to use for cold items within my insulated bags. These are great since they stay cold for hours, aren’t too big or too small & very thick material so I’m not concerned with them ripping. I followed the directions to add water & freeze them (using a measuring cup for 28oz if i remember correctly) comes with a little funnel, plugs & the bags already had the stuff in them that turns into gel so was not hard to set up at all! I haven’t had any issues with leakage & they are made of a good material that holds up! For the price, I made out pretty good! Would definitely recommend!

The size of the bags are perfect for keeping items cold. They do not leak, they look sleek, and they don’t weigh much at all! The Money we spent on these was a great value, and they works great!

Keeps my soda in the lunch box ice cold.

Purchased these to use in a large portable swamp cooler and they were easy to fill and freeze but don’t last longer than 4 or 5 hours as the cooler flows room temp water over them constantly so I purchased the large and small sizes so my Son can swap them out. They will last a lot longer in an ice box and highly recommend them!

I bought some Sunlug and some of that big brand name at the same time, just different sizes. I honestly can't see a difference between Sunlug and the brand name. Drinks stay frosty cold for hours without needing ice - two of these standing vertical in the cooler, cans lined up on either side. We use it for taking a cooler up to the field on hot summer nights to listen to bands, and the last drink pulled out is just as cold as the first, without buying ice or dealing with melted water in a soft sided cooler every week. I even loaned one to a friend last night who didn't have any ice -- one Sunlug in his cooler, put his 6 pack cans on it, and he was refreshed all evening. This morning, after being by itself in a 20 can empty rotomold cooler overnight, the Sunlug was still cold and only partially melted. He plans on buying his own now.NOTE: We made the mistake of topping off a Sunlug-loaded cooler with some ice for our first long trip. At our first stop a few hours later, we had to pull the road drink cooler out of the back seat and whack at the solid block of ice that had formed to get any drinks out. The Sunlugs refroze the ice that was added! It really is colder than ice!!
