保温ランチバッグ

The 35-centimeter length fits perfectly in my work tote without taking over the whole bag. Even after carrying it around all morning, my sandwich was still cool at lunch.

I was pleasantly surprised by how slim this bag is—only 3.5cm thick—so it slides easily into my work backpack without bulging. Kept my sandwich cool for hours during a morning hike.

The insulation is surprisingly effective for such a slim bag—my sandwich stayed cool for hours. At 215g it's light enough to toss in my backpack without adding bulk.
