Opah proudly unleashes Fathom 4, a premium UV resistant fishing cooler bag that is 100% waterproof. That’s right! No more leaks!

Fathom 4 is made with marine-grade vinyl and utilizes an insulation system that allows for long term cold storage of approximately 85-quarts. No need for an ice chest with this quality fishing bag. Plus, every Opah cooler bag is fully washable and mildew-resistant for easy maintenance.

The Fathom 4 fishing cooler is designed to maintain its upright position while being filled and includes an interior waterproof pocket to store filets, beverages, or anything else you want to keep separate and cold. Exterior netting compartments and a spacious pocket with Velcro closure are perfect for storing fishing tools and accessories.


*Note: Due to the high density of foam and the contour of the bag, the dimension of the bag may vary in Length, Width, or Height in the range of 2-4 inches.*

"Filled with ice and kept fish very well. Bag didn’t leak and after done using I just rinsed out with plain water. No fishy smell. Opah bag is a quality product. Very heavy duty."
