This cooler bag is about 10L. It can be filled with a lunch box and some fruit and drinks. The front pocket is for some small things. The outer material is 600D/300D polyester with PVC coated which is very durable. Adjust shoulder strap is easy for  carrying. The lining can be white PEVA, gray PEVA or aluminum foil which is safe for food contact and easy cleaning with damp cloth.

We usually use 4mm thick EPE foam between outer and lining to keep warm or cold. Of course you can use thicker one.

Every year, we supply about 50-100 new patterns for all over world clients. Customized design is also welcome. We have very strong sample room. Send me your artwork, samples will be back to you.
