6 Pack fitness backpack, never used. Tons of pockets, has the freezable cooler packs still in the food storage area, no meal prep containers. Hubs decided it was too big when he got it, forgot to return it, and threw it in the back of a closet. The included freezer packs are two 6x6.5" and one 6x10". Unfortunately they do not say how many ounces they are.
