This is a 28L cooler bag that folds down, with straps for different modes of carrying and additional compartments on the front. Our old cooler bag, a little larger than this one, survived several years before falling apart and I was hoping to get something a little neater and easier to store as we’re short on space. This fit the bill nicely. The inside is foil and it’s quite a simple, straightforward cooler bag. What I love is that there’s extra thought put not it, like with the carry handles on top and the shoulder strap so you can choose how to carry it, and the open pocket plus zipped pocket on front, which would come in handy for picnics and such. It’s a good size at 28L. When it arrived it was folded down and looked quite small so I thought I’d made a mistake on the sizing. When you pull it up to full size, it provides ample for our needs.
