Titan by Arctic Zone Deep Freeze Ice Pack- (2 Pack) 600 Gram High Performance Ice Pack - Long-Lasting, Puncture-Resistant Cold Pack Filled with Non-Toxic Gel… | Reusable ice pack for use in cooler or lunch box to maintain long-term cold for food and drink

AMAZING QUALITY. Lasts cold a very long time, I used it on daily basis. Highly Recommend!!!

Strong material, better than alternative freezer packs and ideal for Titan rucksacks

I wish I could rate this product 10 stars! We already own two coolers that utilize this exact cooling technology, so picking up these spares means we are always prepped and ready to go. Every single claim about their performance is absolutely true. They work wonderfully under normal conditions, but yesterday they completely blew me away. I had just put these new spares into the freezer when, about 45 minutes later, we received an unexpected invite to go swimming. We quickly loaded up our cooler with Gatorade, grabbed the ice packs, and headed out. Because of the quick turnaround, the packs were nowhere near fully frozen; they just felt moderately cold to the touch. The drinks were already chilled, but I was skeptical about how long they would stay that way. To my absolute amazement, these packs kept our drinks refreshingly cold all afternoon, even while sitting out in the direct sun during a brutal 107°F heat index day. The build quality is excellent, featuring a soft exterior that feels tough enough to resist accidental punctures or leaks during transit. Since they are filled with a safe gel that consists mostly of water, I feel completely comfortable packing them right next to our food and beverages. They are quite large, which is ideal for maximizing chilly temperatures in a full sized cooler or a heavy duty tote, though you might find them a bit too bulky for a standard school or work lunch bag. If you need reliable, long lasting cooling power that performs even on a tight schedule, these are a total slam dunk. Pros & Cons Pros: Phenomenal temperature retention: Kept drinks cold for hours in 107°F heat index conditions, even without being fully frozen. Rapid chilling: Proven to deliver noticeable cooling performance after just 45 minutes in the freezer. Safe and durable construction: Made with a puncture resistant exterior and a safe, non toxic formula. Perfect companion pieces: Designed to fit seamlessly as replacements or extras for existing Titan Deep Freeze coolers. Cons: Size constraints: The large footprint is excellent for big coolers but likely too massive for small, everyday lunch boxes.

Buen producto, llegó en bolsa de Amazon pero venía bien protegido.

It works as expected, nothing more to say.

Really good icepacks. I used them on a long road trip. I chilled my cooler in advance using the icepacks, then added cold, refrigerated foods to the cooler, closed it up. The packs kept everything very cold, including dairy, meat etc for my entire road trip one way. On the way back home from my road trip, I did exactly the same thing. Worked great. The outside plastic cover is quite thick, so I doubt the would puncture or crack anytime soon. Even if they did, they'd be easy enough to hot seal with something like a flat iron. Use your imagination ;-) I'm sure the quality of your cooler will dictate how well these work as well, and don't expect to put room temp food in there & have the ice last forever - logic. Be smart about using them, chill your food / drinks in the fridge the night before, use a decent cooler (mine is a hardside Coleman cooler) and they will serve you well. These icepacks never did completely defrost or go soft over the period of a 72 hours, with my food sitting in there in my hotel room. I then drove another 5 hours without refreezing them, then chucked them in to the freezer at my destination until I needed them again. Haven't used them for camping yet, but wouldn't hesitate to do so.
