MIYCOO Cooler Backpack - 40 Cans Insulated Backpack Cooler for Men & Women, Portable 2 Leak Proof Compartments Coolers Bag for Beach Travel Picnic Lunch Hiking BBQ Camping

I've been using this for about a year and it's held up well for the price. https://www.amazon.com/Cooler-Backpack-Insulated-Compartments-Camping/dp/B0DFWG2BNM Sides hold playmats, top holds dice+tokens, front can hold a trade binder if need be. And can usually fit around 10 decks with my more bulky deck boxes.
