Insulin Cooling Wallets & Pouches
Insulin cooling wallets: keep your insulin cool without electricity
Kaio-Dia’s Dia-Cool insulin cooling wallets keep your insulin pens and vials, eye drops and any other temperature-sensitive medicine cool by evaporation. No electricity, batteries or ice packs: soak the cooling insert in cold water and the wallet is ready.
Choose your size below, from one pen for everyday use to four pens or eight vials for longer trips.
How the Dia-Cool works
Soak the cooling insert in cold water: it then cools by evaporation for about 48 hours, and sometimes longer, depending on the outside temperature. To reactivate it, simply soak it in cold water again. All Dia-Cool sizes work the same way, and a replacement insert, the Dia-Cool Pack, is available.
Choosing the right size
Dia-Cool wallets come in four sizes for pens: 1 pen, 2 pens or 2 vials, 3 pens or 5 vials, and 4 pens or 8 vials. For vials and eye drops only, there are wallets for 1, 3 or 4 vials. Several designs are available, for adults and children.
For cold weather: Kaio-Emergency Pack and Kaio-Insulated Pack
The Kaio-Emergency Pack holds two insulin pens or two EpiPens and already comes with a cooling pack. For cold weather, the Kaio-Insulated Pack fits the Kaio-Emergency Pack only.
Care
Hand wash in lukewarm water.
