The FRIO Travel Wallet is a fantastic device for transporting your Enbrel, Humira, or [insert medication that must be refrigerated here] while traveling. These nifty wallets are marketed to diabetes patients, but will work for us arthritic folks as well. All you have to do is immerse the wallet in cold water for 5-15 minutes. This simple act will turn the pouch into a lean, mean, cooling machine! Your meds will stay cold for 45 hours, without any need for refrigeration or ice. The product can be used over and over. Even better, once you put the wallet in its outer cover, you can pop it in your bag without any worry of causing dampness. Brilliant!
