Best fireproof duffle bags

Top pick: FLASLD Large Fireproof Document Bag, 24x12x12" — it's the one bag here that actually matches the size you asked for and is built as a fireproof document bag, with a zip closure and a large flat profile that suits papers, passports and cash.

Who the others suit:

• Large Fireproof Document Bag 24x12x12 with Fireproof Folder (Walmart) — same size class and it comes with a fireproof folder inside, so it's the tidier choice if you're storing loose documents.
• Upgraded Fireproof & Waterproof Document Bag (ALORVA) — silicone-coated fiberglass, the most heat-resistant style of construction, but smaller than 24x12x12, so it's for a compact grab-and-go kit.
• fireproof waterproof travel duffle with lock (Glowrelle) — the only fireproof duffle with a lock, but it's a smaller 43L body, not the dimensions you specified.
• K-Cliffs Heavy Duty Cargo Duffel 24 inch (Target) — right length and tough, but it's a cargo duffel, not fireproof.

Note: fireproof bags are rated for short exposure, not for being inside a burning room — keep documents in the inner sleeve and the bag where you can grab it.
