KonaLarge Ice Pack for Coolers [Blue Ice 4lb] Extreme Long Lasting Design Absorbs Heat to Cool Faster - Refreezable. Reusable. Colder Than Ice (-5C) Cooler Ice Pack

Kept my stuff cold during two days of car travel. Large size and did not sweat and make things wet

Bought these for our Yeti for vacation. Worked perfectly. Highly recommend. Thanks again.

So there was a little bulge even after squeezing the air out but nothing crazy. Keep it my deep freeze which is -17F. After a long day of it being in my cooler that sits in a hot van, it still 90% solid& very little slush. Though I needed 2 but one is sufficient for my needs. Happy with purchase

First, the amount of water that it instructs you to add to each pack, a very specific amount so you don't bulge and/or damage your ice packs, is too much and will bulge and or damage your packs. Idr the amount it says, I threw the paper away, but add less water.I put the exact amount of water that it said to add to the powder, shook it up and put them in the freezer and checked them the next day. Both packs had a pretty large bulge, that had it gone much further would have cracked the plastic. Put both packs in the sink for 36 hours, they were both thawed but still very cold, squeezed ~½ cup of gel from each pack and put them back in the freezer.They are thick plastic and will take a lot of abuse. I have no doubt that would keep a cooler chilled for days.-1 star for the instructions

Keeps my yeti cold for a long time and takes up have the space as a bag of ice. However the only down side is that it thaws very slowly by design(to last longer than ice) so using it to chill say a case of beer that’s not already cold is going to take forever to chill.

This is a great product because of the long-lasting freezing capability, convenient handle and larger size. I would definitely recommend this product.

Does not stay cold for very long. I still have to go to the store and buy ice.

I was hesitant on paying so much for ice blocks but they seems to stay frozen a very very long time and I’m very impressed. Happy I don’t have to buy ice all the time for my coolers
