Collection: Insulated lunch bags and sleeves

Here you will find both insulating sleeves that fit YumBox's large 5-compartment lunch boxes, as well as YumBox's even larger insulated lunch bags where you can put in any lunch box along with an ice pack, fruit, yogurt, a small water bottle, etc. and keep it cool over time. Great for nurseries and schools where refrigerators are not used, or for trips and picnics.
