Cooling Pouches For Insulin, Epipens, and Temperature-sensitive Medications

When activated as instructed, the Chiller Cooling Pouches keep your insulin and medication cool between 64–79°F / 18–26°C for at least 45 hours, even in ambient temperatures up to 100°F / 38°C.

Yes, and that's what makes the Chillers so convenient, as they are reusable indefinitely.

When 45 hours are up — or as soon as you notice the gel starting to diminish and re-crystallize — simply submerge the inner wallet in water again for 2–4 minutes to reactivate it.

There is no limit to how many times you can reactivate it, meaning the Chiller can keep your medication cool for days, weeks, or months of continuous use with nothing more than access to water.

It's very simple. Submerge the inner cooling wallet in cold water and soak for 20–30 minutes. Then manipulate the wallet to evenly distribute the crystals across all panels. Gently towel dry, then leave to air dry for approximately 5 minutes so the crystals can absorb any remaining surface moisture. Once semi-dry to the touch, place the activated inner wallet back into its outer protective cover, add your medications, and you’re ready for up to 45 hours of temperature-controlled medication storage.

The Chiller Cooling Pouches are designed exclusively for heat protection — they maintain medications cool between 64–79°F / 18–26°C.

They are not suitable for insulin or medications that must be refrigerated (36–46°F / 2–8°C).

💡If your medication requires refrigeration, please explore our range of mini fridges and refrigerated travel cases.

The Chiller Cooling Pouches for Insulin & Medications use a two-part system:

• an inner cooling wallet containing specialized crystals
• and an outer protective cover.

When soaked in water, the crystals absorb the water and form a gel-like substance. As that moisture gradually evaporates, it naturally absorbs heat from the surrounding environment — the same principle that makes sweat cool your body.

This controlled evaporation process keeps the interior of the pouch within the safe room-temperature range of 64–79°F / 18–26°C for at least 45 hours, even in outside temperatures as high as 100°F / 38°C.

It’s easy to tell by look and feel. When fully active, the crystals have absorbed water and the inner wallet feels soft, flexible, and gel-like — you’ll be able to see and feel the gel distributed across the panels.

As the evaporation does its work, the gel gradually decreases and the crystals begin to return to their original dry, granular form.

When you notice the wallet starting to firm up and the gel visibly diminishing, that’s your cue to reactivate. If you’re ever unsure, a quick touch tells you — soft and pliable means still active, dry and grainy means time to reactivate.

Yes, and this is one of the Chiller’s most important advantages. The only thing required to activate the Chiller Cooling Pouches is water. No freezer, no power outlet, no USB cable, no power bank.

This makes them ideal for situations where none of those are available: camping, hiking, travel to remote locations, long road trips, school, or work environments without a freezer. As long as you have access to water for reactivation every 45 hours, the Chiller will keep your medications cool indefinitely.

The Chiller Cooling Pouches for Insulin & Medication come in four sizes to match how many injection pens or devices you carry.

• The Small Pouch (1 pen) is the most compact and suits users who carry a single insulin pen or EpiPen daily.
• The Medium Pouch (1–2 pens) adds room for a second pen or small accessories.
• The Big Pouch (1–3 pens) is well suited for users managing multiple medications at room temperature.
• The Large Pouch (1–4 pens) is the biggest option.

ℹ️ Check the product images for the exact internal dimensions of each size to confirm your pens fit, or contact our support team if you have any doubt.

Yes. The Chillers are ideal cooler bags for GLP-1 medications.

Once opened, GLP-1 medications need to be kept cool at room temperature below 77–86°F / 25–30°C depending on the brand, which is exactly what the Chiller does.

The Medium size fits 1–2 standard GLP-1 pens, and the Large fits up to 3–4 depending on pen format.

💡For unopened GLP-1 pens that must be kept at fridge temperature (36–46°F / 2–8°C), you will need one of our refrigerated travel cases instead.

Yes — and this is one of the use cases the Chiller Cooling Pouch is specifically designed for.

Epinephrine injections like EpiPens must be kept within 68–77°F / 20–25°C and should never be exposed to extreme heat or cold. The Chiller maintains the internal temperature well within that range, and its flat, lightweight pouch format makes it easy to carry an EpiPen discreetly at all times — in a backpack, a school bag, a pocket, or a first aid kit.

Any medication that needs to be kept at room temperature below 79°F / 26°C.

This includes open, in-use insulin pens and vials, GLP-1 injections (Ozempic, Wegovy, Mounjaro, Zepbound, Saxenda, Trulicity, and others), EpiPens and other epinephrine injections (Auvi-Q, Adrenaclick, Symjepi, Twinject), glucagon emergency kits, biologic and autoimmune injections (Humira, Enbrel, Cosentyx, Dupixent, Kevzara, Taltz, and others), migraine injections (Aimovig, Emgality, Ajovy), growth hormone pens, multiple sclerosis injections, cholesterol injections, eye drops, and many more.

Yes — the Chiller is one of the most child-friendly medication coolers in the 4AllFamily range. There are no buttons, no cables, no settings, and no electricity required.

Once activated by an adult at home, a child simply places their medication inside and carries it through the day. The flat, slim pouch slips discreetly into a school bag, a backpack pocket, or a lunchbox without drawing attention. Reactivation only requires water, which a child or teenager can easily do on their own when needed.

Yes. The Chiller Cooling Pouches are TSA-compliant and can be carried through airport security in your hand luggage.

The inner cooling wallet, when activated, contains a gel-like substance — make sure to bring it semi-dry rather than dripping wet through security to avoid any questions. Always carry your medications inside the pouch to demonstrate medical use.
