Sometime I need a bit more room for lunch and drinks - I work a 12 hour stretch - and had been looking for a larger insulated lunch bag. This bag is PERFECT!!! Stays cold all day with added cold packs and holds lot of stuff - snacks, drinks, fruit, etc.. And - everyone I know has the 31 bags so I was looking for something different. LOVE LOVE LOVE this bag!!!! Easy to carry too!!!
