Here’s the truth I’ve learned after years of sad lunches: the container matters more than the bag. A cheap bag with a great thermos wins every time.
Don’t fall for the “insulated bag” hype. Look for thick foam walls. Look for a bag that feels like it could survive a minor car crash.
And for the love of all that is hot, avoid glass containers if you’re using a microwave. Glass gets hot. Then it breaks. Then you cry over your lost chili.
