This is a "To-Go Sack"  – A reusable roll-top pouch that emulates a brown paper bag in the original penco design. The Velcro pouch makes it easy to take out the contents, and can be used as a pouch for outdoor activities and sports.

It can also be folded compactly when not in use. Although it does not have a cooling effect, it is recommended as a lunch bag as it has a removable inner backing on the bottom so it holds upright. 

Dimension: (W)7.85" x (H)7.5" x (D)4.1" 
Material: Nylon

* Includes a removable plastic lining for the bottom of the bag
