User questions & answers

Question:	I see two different dimensions listed. Are these 5” x
Answer:	There is no XL to my knowledge. They sell 3x lg(meaning 3(times) large packs). Dont worry, i was trying to find the water volume for XL too!
Question:	Are these TSA approved
Answer:	I just did a test: yes, but just barely in fresh water. I think there is a small amount of air in the frozen packs that keeps them buoyant.
Question:	How long do these stay frozen in a cooler
Answer:	aI believe what they mean is that the latent heat point for the melting phase (transitioning from solid to liquid or liquid to solid without changing temperature) is 18 Degrees F, whereas pure water (note the pure) transitions at 32 Degrees F. This is a big deal because the energy difference between 18 and 32 means it will absorb a lot more heat for a relative temperature rise. 32 to 40 is only 8 degrees whereas 18 to 40 is 22 degrees, almost 3x the amount.
Question:	is that water inside of it? or Gel
Answer:	Mine have stayed frozen for approximately 9-10 hrs. I left food in the cooler,which was well-insulated, and it which was still cold when I got home. This was kept in office setting with temps in room in the 70’s.

• Provides localized intense cold for items in need of quick cooling
• Eliminates mess of melting ice
• Reusable block extends cooling performance
• Packaging may vary

Question:	How long do these say frozen if being used in an insulated bag in the summer time? Thanks in advance
Answer:	I used 2 of these, along with a couple other frozen ice packs. After an 8hr work day as a plumber riding around in my van the packs would still be slightly frozen. The quality of the bag will play a big factor.

Answer:	$1.99 is for one ice pack

Colder, Faster, Longer

An ice alternative that far outperforms ice, 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 and your sandwiches won't turn soggy from melting ice. 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) both freeze more quickly and transfer chill in a cooler more effectively.

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).

Longest Lasting

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.
