A 4L insulated cooler tote in versatile Black that keeps a packed lunch and drink cold for hours.
About this product
The RFF-0041 in Black is THERMOS's insulated lunch tote for anyone who wants the cooling performance without a bag that looks like a lunch bag. It shares the same 4-layer Isotech insulation, 4L capacity, and mesh cooling-pack pocket as the rest of the RFF-0041 line, in a versatile black finish that pairs with a work bag or backpack.
How to use
- Load your bento box, then add a chilled ice pack (sold separately) into the mesh interior pocket against the food.
- Zip the bag fully closed — leaving it open lets cold air escape and shortens insulation time.
- Hand-wash the exterior fabric only, air dry, and wipe the interior lining with a damp cloth between uses.
Ingredients
- Exterior fabric — water-resistant polyester with THERMOS Isotech multi-layer insulation lining.
- Interior mesh pocket — holds a separate ice/cooling pack (not included) against the food compartment.
- Care — soft carry bag, not a food-contact container; hand-wash exterior only, wipe inner lining with a damp cloth. Not dishwasher or microwave safe.
FAQ
Does the black colorway perform differently from the other colors?
No — all RFF-0041 colorways share the same 4-layer Isotech insulation and 4L capacity, just different exterior fabric colors.
Can this be machine washed?
No, hand-wash the exterior only and wipe the insulated interior with a damp cloth.
Does it fit a drink bottle alongside the bento box?
Yes, the 4L size fits a single-tier bento box plus a small bottle.
🇺🇸 For US customers
Black is the most versatile pick in the bento-carrying trend that's been running through lunch-prep TikTok — it works as a gym bag insert, a work tote add-on, or a standalone lunch carrier without looking out of place. Real insulation and a cooling-pack pocket set it apart from a plain fabric lunch sack.
