Fit my needs perfectly!

I am from Alaska, where cooler bags aren't used as often. I heard about Opah from a few friends that do salmon charters and knew I needed to give one a shot. The Fathom 4 makes Salmon fishing on my small boat so convenient. I can take the bag and put it right in my SUV without worrying about leaking. Ice lasts FOREVER! Awesome product!

Good quality

Haven’t use the fish bags yet. They seem like there very good quality

Great bag

This Fathom 4 fits perfectly up front of my W/A cuddy . I use it on Lake Erie walleye fishing. Holds my day catch & opens up my fishing deck to give us more room. I usually fish 2/3 people so 12/18 fish for a days limit. Would add another bag this size if fishing 4/6 people.

Thank for the great review, Davey. It is very helpful to hear your breakdown of your typical fishing experience. We also appreciate you abidding by catch limits and helping the fish ecoenviroment. When you are ready for that bigger fishing group, we are ready to help you add another Fathom 4 bag!

Fathom 4

Excellent quality and holds ice better than the other high quality fish bag I’ve come across!

Thank you, Michael, for the great review. It looks like you have used some other products, but we love to hear that our quality and usefulness superseded other bags you have used in the past. We look forward to keeping your catch fresh and cold!

Opah Gear Review Out Of the Box

I really love everything about this bag. Only “disappointment” is -the zipper stitching does not go all the way to the ends. As it sits, if it ever fell over- you would have massive leakage in the back of your pickup/car/boat because of this. I also feel if you stitched it all the way however it would become a true “dry bag” and would probably need a different zipper system all together… I think the zipper matches the other zippered kill bags on the market so its not a stopper from buying the bag in my opinion.

Thank you, Christopher, for your review. We are always open to ways to improve our products. The way we build our bags with the flat bottoms prevents the possibility of the bag tipping over, even through rough waters. Our zippers are built to take on the elements (salt and sun), while keeping your catch nice and cold on the inside.
