The Original Puffy Cooler™. Fold it into the built-in stuff-sack to fit in your carry-on, purse, or pack. Less Lugging, More Living
The Mayfly is the smaller Monti Cooler, built to go anywhere and still keep things cold way longer than you’d expect.
Use the roll-top for peak performance and comfort. We also find the product performs best with ice packs rather than ice in higher humidity environments if you are concerned about condensation.
