Ninja FrostVault 4lb. Ice Pack, Reusable, Refreezable Ice Block, Mess Free, Recyclable, Designed to Fit Ninja FrostVault

I have the Ninja 50 and I used two of these blocks on the bottom and then I had previously purchased the XL igloo blocks (they were too big to both lay flat). Since there is a gap between the two ninja blocks I used one of my igloo blocks as a partition. I decided to go camping with zero ice. Day before camping it was 91 and I put an igloo block in the cooler to precool it, worked perfectly. Then day 1 camping it was 93 and I packed it as described above and everything in the top was beverages. The drawer had fruits and vegetables and hummus. Camping day two was about 80 degrees and day 3 was much cooler till I got home and left the cooler in the car and it was about 81 degrees outside, left in their for HOURS because I was too tired to unpack. But once I did everything was still super cold. The ninja blocks had defrosted and it’s hard to tell if the igloo was fully defrosted but all the drinks were ice cold and the drawer snacks still fresh and cold. Cooling performance was 5 star, but I’m sure the igloo block was a big contributor as they are much thicker. I’d say the price was reasonable as the igloo blocks were about the same price. I give it 5 stars but for some reason it’s only marking 4.

Vraiment bon, garde les aliments au frais au moins 3 jours!

pricey little boogers. But without a doubt, the best ice packs I’ve ever bought. Highly recommend, especially if you have a cooler with room form.

Un peu cher, mais comparer au bloc régulier, il dure beaucoup plus longtemps et garde ma glacière froide plus longtemps et plus froide

This freezes well and goes perfect with the cooler. No need for bag ice anymore. Would highly recommend
