When it comes picking a kids lunch bag for the new school year, the choice is pretty easy. No other insulated lunch bag has built-in cooling that lasts as long as PackIt. And only PackIt can keep healthy food safe and delicious all day. But with dozens of styles to choose from, how do you pick just one? Here's our handy guide to the best bags for your crew by age and stage.

Preschoolers & Elementary Schoolers

For little ones away from home for the first time, our Freezable Lunch Box, is your best bet. Finicky toddlers need multiple options to keep them pleased, yet you don't want to weigh them down with too much food that they can't carry the bag. This is a fun twist on the classic lunch box shape. It has a convenient top-load design and diagonal hinge so your child can access food or drinks on the go without having items fall out. There's also a slim zip pocket on the front for ID cards, bus passes and napkins.

Freezable Upright Lunch Box and Freezable Lunch Bag

Now that they're spending a full day in class, grade schoolers are ready to upgrade to our flagship Freezable Lunch Bag. This best-selling lunch bag is beloved by millions of families because it doesn't need ice packs to stay cool, so your child will never accidentally throw them out. It also folds up neatly for the ride home in your kid's backpack. Trust us, this might be the only lunch bag your child won't lose within the first month of school!

Both styles come in a variety of cool patterns and have a convenient buckle handle that attaches to backpacks and sports bags. You really can't go wrong either way!

Lunch Bags for Middle/High Schoolers

Freezable Classic Lunch Box and Freezable Traveler Lunch Bag

If your kid is 13 going on 30, you know that lunch bags that seem babyish or boring just won't cut it. They've got to be cool inside and out. Our Freezable Classic Lunch Box is a nice option for middle schoolers in that tricky in-between phase. It offers the traditional lunch box design with more sophisticated patterns that the style-conscious students will love. The roomy interior fits large bento boxes and containers of all shapes.

Capacity of the Freezable Classic Lunch Box

By the time kids are ready for the big leagues of high school, appearances are everything. Our Freezable Hampton Lunch Bag is a handbag-style cooler that will definitely turn heads in the lunch room. It's easy to carry in hand and has plenty of room for a full meal and snacks.

For student athletes, we love the Freezable Lunch Bags. It's made for lunch, but its tall profile is particularly handy for taking multiple water bottles to sports activities as well.

Lunch Bags for College Students

Freezable Uptown Lunch Bag

Now that they're in the "real world," it's time for a grown up cooler. The Freezable Lunch Bag is our top pick for the student that's always on the go. They're often so busy they forget to eat at all, or they fall prey to the 3 am pizza run during late night study sessions. Having healthy options on hand in the Uptown ensures they make better choices. It's also a great lunch cooler for internships; the sleek design will make a stylish impression in the workplace.

For older students, the Freezable 15-Can Zuma Coolers are a smart college send-off gift. They not only chill food (the Freezable 15-Can Cooler makes the perfect personal lunch bag), but they're also awesome for taking beverages to tailgates or hydration to intramural sports.
