We tested 26 lunch boxes for 
L.L. Bean Lunch Boxstyle and safety -- here are the four winners.
When it comes to packing a healthy lunch for your child, it isn't just about the food, but also about making sure it stays at a safe temperature.
Of the 26 lunch boxes and bags we tested, these six kept food at the recommended 40 degrees or lower for two hours or longer. The bags also scored well in usability - they're easy to open and close, pack, carry, and clean - and their style is kid-friendly.
