Pack Ahead Freezable Lunch Bag - Foldable, Reusable with Built in Ice Packs

Fits two Sistema sandwich boxes plus a two-egg case and some camping utensils and keeps everything cold for at least a couple of hours. Bundles up nicely for freezing a pair of them.

It doesn't stay cold as long as some other brands. I was disappointed!

Does not keep anything cold for more than a hour. Gel packs thaw way to quick to be useful. Would not recommend to anyone.
