Product Description


Cooler Shock vs. Regular Water
Ice starts out at freezer temperature and will warm fairly quickly to its melting point (32 degrees F). Once at melting point, the ice will stay at the same temperature during the whole process of melting. After fully melting, the liquid starts to warm normally again.
Cooler Shock ice packs also start out at freezer temperature, and will warm pretty quickly, but it's melting point is at a much lower temperature — 18 degrees F. During the whole process of melting, Cooler Shock stays at this lower temperature. This lower melting point means that when ice begins melting and warming in your cooler, Cooler Shock packs still stay cold, even as they begin to thaw.
Frequently Asked Questions (FAQ)
- Do I need to refill the packs? No, you do not need to refill your Cooler Shock packs. Once they are sealed, they should not be opened or emptied.
- Can I use my Cooler Shock packs in the refrigerator? Cooler Shock packs are expertly designed to provide the best cooling energy when frozen. We do not recommend using Cooler Shock packs in the refrigerator because your fridge does not usually get below 32 degrees F (a.k.a. freezing temperature).
- What is the difference between the zipper packs and the screw cap packs? Essentially, nothing. The packs contain the same ingredients. The only difference is how you fill and seal the packs at home. The zipper packs require an iron to seal, whereas the screw cap packs use a funnel and cork (provided) to create a leak-proof seal.
- How long should Cooler Shock packs be frozen before use? We recommend 48 hours for large packs, 24 hours for mid-size packs, and 12 hours for lunch-size packs for best results.

Colder, Faster, Longer
Cooler Shock Premium Ice Packs (Large)
An ice alternative that takes “cool” to the next level, Cooler Shock reusable ice packs are designed to provide extended cooling at 18 degrees F that can last up to 48 hours.
Great for camping, picnics, boating, fishing, tailgating, and any perishable transport (both personal and commercial), Cooler Shock ice packs turn warm drinks ice cold in the cooler without turning your sandwiches soggy from melting ice. After a day of fun, just return Cooler Shock to your freezer and they'll be ready for the next outing.
DIY Reusable Bags — Just Add Water Once
Cooler Shock ice packs are shipped dry with a proprietary cooling gel mixture inside that turns into a solid block when frozen. Just add water at home, shake, and seal to create reusable ice packs that can be used over and over.
Choose from two closure types:
- Screw cap with cork and included funnel for filling.
- Zipper version that's sealed permanently shut with an iron.
Thin, Durable Construction
Cooler Shock's flexible, multi-layer bags are made with aluminum and polyethylene to keep the contents secure and reinforced with thin nylon to help strengthen the pack.
Measuring about one-fifth the thickness of rigid ice packs, Cooler Shock's thin walls (8 mils, or about 0.2 mm) freeze quickly without losing cold-transferring effectiveness.
Key Features & Specs
- Large size ice pack — 10 x 14 inches
- 1 large pack replaces 6 pounds of ice
- Shipped with dry gel mixture — add water and seal at home
- Screw cap closure with cork and included funnel
- Each pack requires 56 ounces of water (7 cups)
Cooler Shock Ice Alternative Outperforms Ice
Superior Cooling
Cooler Shock's proprietary cooling gel mixture is more dense than ice and uses a scientific phase change formulation, providing a higher energy concentration for sustained cooling at 18 degrees F (read more below).
Cold Up to 48 Hours
When paired with a high quality cooler, Cooler Shock ice packs will keep your food and drink chilled longer — up to 48 hours for Large and Medium packs, and up to 8 hours for Lunch packs.
Reuse Over and Over
Return Cooler Shock ice packs to the freezer after using and they'll be ready for your next outing.
Affordable & Convenient
Cooler Shock ice packs will pay for themselves in just a couple outings (compared to the cost of 10 to 20 pounds of ice) — and no extra trip to the store.

- Reviewed in the United States on June 18, 2024Style: All Purpose Size 4-packVerified PurchaseThese were purchased to fit in the 16 quart Coleman hard-sided cooler. They fit perfectly. I put one on the bottom and one on top. I purchased the lunch sizes for the sides. Once the set-up is done, and they are frozen, they are easy to use and keep your cooler COLD! They work well!
SET-UP: you have to fill them up with a specific amount of water. You need to use the funnel (comes with one) to fill them up. You should measure out the correct amount of water to fill them, but I have filled these in other sizes and once you've done it enough times you know about when to stop. If you aren't experienced with when to stop, then definitely measure out what you need so you have enough in there and don't overfill. Once they are filled with water, you squeeze a stopper in the top and close it tight all the way. The stopper can be difficult to push in, but make sure it's down as far as you can get it before trying to put on the cap. Then put them in the freezer FLAT. Unless you are looking to purposely shape them, keep them flat for best use once frozen. They were frozen by next morning and ready to go.
USE: I put two of these and two lunch size in a hard-sided cooler and they kept the items cold for 36 hours. Impressive. They were about half to 2/3rds melted when I put them back in the freezer, flat again, and then next morning, again they were ready to use.
TIPS:
1. If you have an extra freezer in your basement or garage, I would keep these in various sizes in there for use in coolers. I also have the largest size that I put in a big Trader Joes soft sided cooler bag for car trips as well. I have packed groceries in and drove 7 hours and popped them in the fridge when got to destination and everything was fridge cold still.
2. If you have a better funnel, use that. The one it comes with is small and flimsy, but works.
PROS:
THEY WORK!! Enough said! Worth the price - which is decent - and effort to set up! Save you money on purchasing food on the road. Have healthy foods from home without the restaurant, convenience store up charge!
CONS:
You have to put in a little work to get them "made" and they need to go into the freezer for 24 hours (will be ready in less if needed but plan on at least 24), so don't buy these last minute. Prepare for their use.
They can take up room in your freezer and get in the way, so best if you have a separate extra freezer to store them in.
- Reviewed in the United States on March 24, 2025Style: All Purpose Size 4-packVerified PurchaseI bought these reusable ice packs for my husband to take to work, and they’ve been a game-changer! They’re long-lasting and keep his lunch cold throughout the day, even on the hottest days. We’ve also used them on camping trips, road trips, and at the beach, and they’ve worked perfectly every time.
They’re super easy to use—just freeze them and pop them in his lunch box or cooler, and they stay cold for hours. The packs fit easily into all kinds of bags and containers, and they’re very durable. I love that they’re reusable, which makes them both eco-friendly and cost-effective. My husband is really happy with them, and it’s been great for keeping his food fresh! Highly recommend them for anyone who needs reliable cold storage on the go!
- Reviewed in the United States on March 31, 2025Style: All Purpose Size 4-packVerified PurchaseThis is an incredible product. It comes with a powder. You add water and it turns into a gel. It takes a while to freeze it, but once you do it is frozen for a very long time. I packed up my black Subaru at 11:00 a.m. on an 80° day with a standard igloo cooler drinks and food and four of these packs. I pulled into work and the cooler stayed in my car with the food and drinks and pack. When I got back to my car after this sunny day everything was still cold and in fact was cold the next morning. These packs are truly incredible and absolutely worth the money.
- Reviewed in the United States on September 4, 2020Style: Lunch Box Size 5-packVerified PurchaseWhen I ordered these with the "some assembly required", I was prepared to be really irritated that I had to do the work to save them the money. But what I found was, it was actually fun putting it together and I was afraid of potential leaks, but out of the 5 I ordered (lunch size), all have had no issues whatsoever, which is surprising as I am not the IKEA assembly guy at all. I expected it would fail and it didn't.... not one drop spilled.
The ONLY reason I gave 4 stars instead of 5 (should really be 4.3 ish) is their claims of 8 hours of "as cold as ice". That may be the case if you are using them at room temp, but I bought them to keep beers cold for a 4-5 hour golf round in 95 degrees and for that, it worked, but was dying after 4 hours and the beer was maybe 40 degrees... I prefer 34-36 degrees. Yes I am a beer prima donna. Skeptical on the 8 hour claim, and that is why I did not give 5 stars. But for what I needed, it worked great!!! Maybe the larger versions were the 8 hour ones. Meh.
But these things coming out of a very cold freezer will burn your hands, be very careful! They are so flipping cold! Protect your hands if using a very cold freezer or you may get frostbite. If you doubt the colder than ice claim, put it in a deep freezer and lose a few fingers if you are not careful taking it out...
Overall, no issues at all with the lunch size pack of 5. Durable, convenient, and definitely way better than ice, and other non-ice solutions we have used. And for me and my wife the money was well spent for sure.
For 5 stars, and this is not just for this product, promise less and deliver a bit more. But this is pretty awesome compared to a lot of other products we have tried. We are considering the larger versions, based on the performance of the smaller items and may update this review based on that. May yet get 5 stars, we will see.
8.8/10 Have recommended to friends and family. Place this in the best triple walled cooler and you may have a cold beer next week... or at least a 40 degree beer....

5.0 out of 5 stars Fantastic Purchase!
Style: Lunch Box Size 5-packVerified PurchaseIt works exceptionally, I am really happy for my purchase. I tried to find the best cost/effectiveness and this was the result, it made me discover that the lunch bags we have has bad insulation. They are exceptionally cold for a minimum of 12 hours (in bad insulation) so I'm excited to use these in coolers for summer camping. Thank you so much for making a great product that's also fun to make! No regrets for this purchase.

2.0 out of 5 stars Gute Kühlleistung, empfindliche Beutel
Style: All Purpose Size 4-packVerified PurchaseAn und für sich eine gute Kühlleistung, allerdings ist einer der 4 Beutel ohne Gewalteinwirkung in der ersten Woche der Verwendung direkt unterhalb des Drehknaufs gerissen und damit unbrauchbar. Bei dem Preis meiner Meinung nach nicht akzeptabel. Mein Fazit daher: Grundsätzlich gut, aber scheinbar sehr fragil, womit es für den Einsatz in der Kühlbox in Anbetracht des Preises zu Riskant ist. Würde ich mit diesem Wissen nicht wieder kaufen.

5.0 out of 5 stars The perfect cool pack!!
Style: Lunch Box Size 5-packVerified PurchaseBrilliant!! I used these packs to keep pumped breast milk cold overnight in a cool bag and in my nappy while out and about. I have also used them to keep a dozen or so bags of breastmilk frozen while travelling.
I use 2 of the packs overnight in a cool bag and the breastmilk is ice-cold - cold enough to put straight into the fridge.
I use 1 pack in the front zip section of my backpack-style nappy bag that holds 3 bottles of breastmilk. The great thing about these packs here is that they are soft when room temperature so I mould them to fit into the small front compartment and then freeze - normal rigid ice packs don’t usually fit.
I have used all 5 in my cool bag to keep my breastmilk bags frozen on 2 trips lasting 3 hours - they were still frozen solid at the end of both trips!!
When I first read the info on these packs, I was worried that the breastmilk would freeze if a bottle was in contact with them. Luckily this has not been the case as you can control the amount of cooling with the number of packs.
These cool packs have taken away so much of the hassle of expressing and storing breastmilk - one less stressor as a new mum!!
