The Westport Insulated Lunch Bag from Fit + Fresh solves the daily struggle of disorganized meal prep by offering a surprisingly efficient interior. The wide top opening makes it effortless to slide in your bento box, utensils, and even an insulated water bottle without a struggle. I was particularly impressed by the thermal construction.
