[KEEP FOOD WARM & FRESH]: The 4-layer insulated men lunch bag is equivalent to an internal temperature circulating system, firmly locking in the temperature of the bento for up to 5 hours (the time it takes for an 80° bento to drop to a 30° bento), and keeping it cold for up to 12 hours in the summer when used in conjunction with an ice pack. Keeps food fresh/temperature for a healthier life. [INSULATED LUNCH BAG WITH MUTI-POCKETS]: The lunch bag has 1 main compartment, 2 side mesh pockets and 1 front zipper pocket.

[PORTABLE]: The size of the tote lunch bag is 25cm(L) x 18cm(W) x 23cm(H)(NOTE: Measurement size is the size of the product after the product is fully expanded, because it is manual measurement, so there may be about 1cm error.), It also can be folded flat for easy storage or travel with 310 gram weight. The reinforced, adjustable and detachable shoulder strap helps free your hands and gets multiple carrying options for more travel possibilities.
