Frio Individual Cooling Wallet for Insulin Pen – Water-Activated Evaporative Cooling in 5 Colours

The Frio Individual Cooling Wallet uses an evaporative cooling system: simply soak in cold water for 5–10 minutes, and the polymer crystals inside absorb and hold the water, creating a sustained evaporative cooling effect that keeps the contents between 18–26°C for 45+ hours — no ice, no electricity, no refrigerator required. Ideal for single insulin pens. Available in Black, Blue, Green, Purple, and Red.

Frequently Asked Questions

How does the Frio Cooling Wallet work?

Frio wallets contain a polymer crystal matrix in two inner panels. When soaked in cold water for 5–10 minutes, the crystals absorb water and swell. The crystals then release water vapour through the outer fabric via evaporation — cooling the inner compartment below ambient temperature. It can be reactivated by re-soaking.

How often do I need to re-soak the Frio wallet?

In hot conditions (above 30°C), re-soak every 24–48 hours. In cooler conditions, the wallet may last 45+ hours before needing reactivation. Carry it in a well-ventilated area rather than sealed in a bag. Never store in a plastic bag while in use.

Does the Frio wallet replace refrigeration?

No. Frio wallets are for in-use pens. Unopened spare insulin should still be refrigerated. Follow your medicine's storage instructions.

What colour should I choose?

The colour does not affect cooling performance. Available in Black, Blue, Green, Purple, and Red.
