This summer I asked readers for suggestions for lidded, microwaveable containers to use for my son's preschool. You had some great ideas and I ended up buying this set which has totally fit the bill. The slim, insulated cooler bag holds three CLIX containers (that click or unclick together) and 3 more CLIX are included for good measure. I use 3 for lunch and 3 for his snacks. I've also used it on road trips with the included freezer pack. The elasticized handle makes carrying easy or it can hold a thermos, sippy cup or banana.
