Bummer - way too small for my needs.

I returned this product before using it
Runs small

I bought the small sized based on the stated dimensions but the dimensions are for the exterior and don’t take into consideration the insulated lip inside. This lunch box will not fit a Yumbox Panino (sandwich style) lunch box inside of it. This would work if you’re planning to pack lunch in baggies but definitely not if you plan to use any sort of lunch container. Such a bummer because if it was just a little bigger, it would be perfect! Now to decide if the medium size is just too big or not! :(

This thing is great!

I've used it several times

The size small is perfect for keeping a sandwich & side cold for 5-6 hours with an ice pack. Mine stays in my work truck, so coldness would vary if you're leaving it out in the heat/sun all day. It also holds four 12 oz cans nicely, so I've been using it for post-ride or hike beers!
