Fill 'er up! This great looking bottle-bag/lunch-pail fits a lot. Put in three tall bottles with room to spare. Use it for your own lunch and put in a water bottle or two, just don't squish your peanut butter sandwich! The 3M Thinsulate lining keeps things cool (or toasty) for snack time. No one will be running on empty when you keep this great accessory filled up. Oh...almost forgot...it's machine washable!
