I picked up this Marine Ultra 24-Can Square Cooler Bag for boat trips and it holds up well in wet conditions. The ultra-thick puncture resistant fabric feels tough, and the UV protection is a nice touch for long days outside. It keeps drinks and snacks cold and fresh without any fuss. The square shape makes it easy to pack and carry. It's not the lightest bag, but for harsh, wet environments it does the job. Solid choice if you need something durable for marine use.
