Clip and go with the Sachi "Style 226" Insulated Junior Lunch Pouch.

This fashionable insulated lunch pouch can be used to transport warm or cold food and drinks.

There are many variables that can affect the length of time food or drinks stay cold. For best results use an ice pack or ice substitute. These will function better than ice cubes as they minimise the amount of condensation or dampness that can occur as ice cubes melt. If using ice cubes we recommend you seal them into a zip lock style plastic bag to protect the items in your bag from melting ice over an extended period of time.

Helpful hints to enhance performance of the insulated lunch pouch:

• Pack the lunch pouch as full as possible with like temperature items. 
• The colder the items are at the time of packing, the longer they will stay cold.
• Place ice packs or substitutes on top of the contents when possible as cold air flows down.
• Minimise opening the lunch pouch to keep cold air in and warm air out.
