FRIO Insulin Cooler Wallets

For anyone managing diabetes away from home, keeping insulin within its safe temperature range shouldn't mean hauling ice packs or hunting for a fridge. FRIO cooling wallets use evaporative cooling — you soak them in cold water for a few minutes, and the gel crystals inside activate to hold insulin cool for roughly 45 hours, even in ambient temperatures up to 100°F (37.8°C). No refrigeration, no batteries, no ice required. Once dried out, simply re-soak to reactivate; a single wallet can be reused for years.

This collection carries two sizes to match how much you need to carry:

• FRIO Duo Insulin Cooler Wallet (approx. 3.25 x 7 in) — sized for one or two pens or vials, slim enough for a pocket, purse, or travel bag.
• FRIO Large Insulin Cooler Wallet (approx. 5.5 x 7 in) — holds multiple pens or vials, ideal for longer trips, families managing supplies together, or anyone carrying a bigger daily supply.

A common question: does FRIO make insulin cold, like a fridge? No — it keeps insulin within the safe "in-use" range (below 78.8°F / 26°C) rather than chilling it to refrigerator temperatures, which is exactly what manufacturers recommend for insulin already in use. That makes these wallets well suited to commutes, vacations, work days, hiking, and hot climates where a cooler bag simply isn't practical.

FRIO products are also useful for other temperature-sensitive medications and are trusted by travelers who fly, since they contain no restricted gel packs or coolants that raise issues at security.
