Hydro Flask Kids Lunch Box review

The Hydro Flask Kids Lunch Box is a carrier, not a bento: it holds the containers and bottle and keeps them cool. Hydro Flask says the insulation keeps contents fresh for hours when paired with an ice pack, and the main fabric is 100% recycled polyester with a durable coating and bluesign approval. It opens with a hinge top, the interior is fully lined so it wipes clean, and the outside measures 3.70 x 12.10 x 10.05 in. at 1.10 lb. Hydro Flask positions it to pair with its kids bottles. That makes it a good partner for a Bentgo or Yumbox, but at $44.95 it costs more than either box and does not include containers or an ice pack. Some colors were out of stock when we checked, and the page carries a California Proposition 65 notice for dimethylformamide. We compared documented features and published prices and did not test it.
