Bentgo Signature Leak-Proof Glass Food Storage 12-Piece Set

Pros

  • Leakproof in two independent tests
  • Glass lids with attached silicone gaskets
  • Borosilicate bowls
  • Microwave- and dishwasher-safe lids
  • 2-year warranty

Cons

  • Heavy
  • Lids suction down as hot food cools; open the valve first
  • America's Test Kitchen found a slight tuna odor on the lids
  • Lids should not go in the oven

The best all-round choice for meal prep and lunches. Plastic-free and PFAS-free status are Bentgo's own claims, but the leak performance is independently backed, which is rare in this category.
