I recently took my full size refrigerator out of my business, but still wanted to get my Amazon fresh groceries delivered at work, since my home isn't in the delivery range. That also means the food is already thawing for an hour before it gets delivered. So, I needed better cooler bags and reusable ice packs that could stay cold for 10 hours before getting the food delivered, and then hold up for another few hours before getting the food home (another 3-4 hours, so the ice stayed mostly frozen for almost 14 hours in these bags). I bought these ice packs after reviewing every product on Amazon, and I got the Titan insulated bags. I avoided ordering things like ice cream or frozen waffles, because I've noticed those don't arrive frozen by the time they deliver the groceries. I mainly ordered frozen meals, mini pizzas and refrigerated stuff. The food was still frozen when I got home! The only thing that thawed were some frozen french toast sticks (I took stuff like that out of their boxes because I figured it would help keep them cold better if they had direct contact to the ice). The refrigerated stuff was plenty cold still too. These ice packs get so cold that it almost burns your hand to touch them. They stay cold for a lot longer than my thin blue ice packs of various brands. They freeze in a nice thin shape, seem to have excellent build quality, and are a great size. I wanted more small ice packs rather than one large one so I could make sure all of the food had ice on almost all sides of it. They actually weigh quiet a bit, which is probably why they can stay frozen longer than the cheaper ice packs that I have. I was really hesitant at first to get these because of the cost, and having to fill them with water myself, but I am so happy that I did! They were easy to set up and do a great job. We actually have power outages pretty regularly and I feel more confident that my frozen food will stay frozen longer with these in the freezer. When you are squeezing the air out of the pouch, after adding water, you can see the material inside the pouch is a light blue color. After it sets for a few minutes it becomes gel inside. So far only the edges thaw out after 14 hours of use. And it does seem to help if they have a full 24 hours to re-freze after use (as opposed to 12).

This review is long overdue but it will show the products longevity. I bought a 4 pack Medium, 2 years ago and they are still going strong. I use them daily on my 12/hour shifts and they do a great job of keeping my drinks and food cold throughout. I have an insulated backpack I carry for my lunch bag. I typically only use 1 ice pack in the cooler months and 2 in the summer and that usually works great! I would buy these again, and will buy them again when my packs wear out....whenever that may be. Full transparency, one of them has cracked, but I still use it. I blame it on operator error though. If you freeze them flat, this should not be an issue. I have let them freeze on more than one occasion with the corners bent. When this happens, it can put a lot of stress on the corners when I shove them down the sides of my cooler and also when I drag items out of my bag. I can't fault the manufacturer for that. I've seen some reviews saying they aren't very durable. That has not been my experience at all. While the new one have changed the logo, I don't think they changed anything else. If they did, that would be a mistake. For the price, awesome cooling, and longevity I personally think they are worth EVERY PENNY! I recommend them to people and co-workers all of the time.

As a Colorado transplant who spends most weekends exploring Colorado's trails, I always seek gear to keep up with my outdoor adventures. These Cooler Shock Reusable Ice Packs have become an essential part of my pack. They ensure that my food and drinks stay refreshingly cold, whether I'm summiting a 14er or just enjoying a picnic in Denver's Cheesman Park. Here's why I'm giving them a 5-star summit salute: Long-Lasting Chill: These ice packs are like the Energizer Bunny of cold—they just keep going and going. They stay frozen for an impressively long time, keeping my more extraordinary contents chilled for hours, even under the intense Colorado sun. No more lukewarm trail snacks or melted sandwiches to dampen my summit celebrations! Durable and Reusable (Just Like My Favorite Hiking Boots): These ice packs are built to last. They're made from rigid, puncture-resistant material that can withstand the bumps and jostles of a day on the trail. Plus, they're reusable, which aligns perfectly with my commitment to sustainability and minimizing waste. Versatile Sizes for Every Adventure: The variety of sizes is perfect for different needs. I use the larger ones for my main cooler when I'm car camping or heading to a Rockies game and the smaller ones for my lunch bag or to keep individual drinks cold on those long hikes. Quick Freeze for Back-to-Back Adventures: These ice packs freeze relatively quickly, so I can easily re-freeze them overnight after a day on the trail and be ready for my next adventure. No more waiting around for slow-to-freeze ice blocks! No Messy Leaks (Unlike My Attempts at Backcountry Cooking): Unlike traditional ice, these packs don't leak or create a watery mess in my cooler. My food stays dry, my cooler stays clean, and I can focus on enjoying the scenery instead of cleaning up a soggy mess. A Few Minor Considerations: While I'm pleased with these ice packs, there are a couple of minor drawbacks that I've seen mentioned in other reviews: Condensation: Some users have reported that the ice packs can form condensation on the outside. I've noticed this, but it's easily managed by wrapping the packs in a thin towel or placing them in a waterproof bag. It's a small price to pay for the convenience and long-lasting chill they provide. Not as Cold as Regular Ice: While these ice packs stay cold for a long time, they might not reach the same freezing temperatures as regular ice. However, they're sufficient to keep food and drinks refreshingly chilled on even the hottest summer days. Overall: If you're looking for reliable, long-lasting, and reusable ice packs for your cooler, the Cooler Shock ice packs are an excellent choice. They're a must-have for hikers, campers, picnickers, and anyone who wants to keep their food and drinks cold on the go. As someone passionate about exploring Colorado outdoors, these ice packs have become essential to my gear, ensuring that refreshingly cold snacks and beverages always fuel my adventures.

The packs get really cold, but I don’t think they last very long. given all the reviews and the research I did, I was expecting the icepack to stay frozen for much longer than it did. We did a 18 hour trip, and I used a high-end small cooler, not yeti, but close, and after eight hours, the medium sized ice pack was totally melted. Still cool to the touch, but I was hoping for longer freeze time. I bought these four, plus three of the extra large size. I had hoped was to use them for camping, where I need things to stay cold for two or three days. My plan was to augment these with bags of ice. But I don’t know that these are really going to stay as cold as I had hoped for. Update: I never posted the above review. Since then, over used these several times for camping. They work great, if you use enough of them for the size of your cooler. I used 3 xl and 2 medium ice packs for a five day camping trip, and after three days, my frozen food was still frozen. But, given how many I used, there was less room for food. I still think the xl yeti is the way to go if you can pony up the money.

These Cooler Shock ice packs are awesome. What impressed me the most is just how long they stay cold. I’ve used them several times now and they keep everything nice and cold for way longer than regular ice without having to deal with all the melted water and mess. I also love how easy they are to throw in just about any cooler. They’re thin and easy to pack in a small cooler, but they work great in a big cooler too. They don’t take up a bunch of room, which leaves more space for the important stuff! Super easy to use, easy to transport, and they stay COLD. I’ll definitely be using these from now on.

These are the best ice packs I’ve had! They really do last 8+ hours in a cooler and keep drinks and food cold. I got the medium sized ones and it’s pretty darn perfect for the cooler I have. Maybe a little smaller would have been nice but not a big problem in my opinion. Great value for the money!

Very very cold ice packs. Definitely colder than lots of other ice pack variants out there. The material is solid and the instructions are very easy. They are easy to fill and freeze. These are the large ones, possibly larger than you may need, larger than you have space for in the freezer but excellent nonetheless. They are barely thicker than a normal ice pack and weigh just about the amount of water you put in them. Shockingly cold and easy to shape into a nicer shape if you prefer that when refreezing. Even after melting, they are cold enough to use! Very nice.

I absolutely love these freezer packs. They are easy to use and versatile, and they are so cold if you're not careful, they will freeze items in your cooler solid. I am sad to report their lifespan is very limited. I purchased these in 2023, and used them for three summer/fall camping seasons. We are heavy campers, frequently going on trips twice a month. I was sad to find these were all oozing when I pulled them out to prep for this year's first trip. The corners appear to be very weak and prone to cracking open. That being said, they are still much less than the cost of three summers worth of ice. If you don't mind that you'll have to replace them, they're a good buy. I just wish they were more durable. I'm going to try the companies hardshell freezer pack option next time.
