If you didn’t know, there are very well designed thermal bags & totes on the market. Practical, waterproof and in various patterns and colors, thermal bag is your best travel buddy. Im always horrified while staying at the beach/ by the pool when I check my phone which is boiling hot or my melted lip-balm. The thermal bags are made just for this kind of troubles.
If you don’t like totes, there are smaller thermal bags that you can easily insert in your stylish bags.
