Keep your catch fresh and your gear organized with the Fathom 3, a premium leakproof fishing cooler bag built for serious anglers.

While built for anglers, the Fathom 3’s tough construction and excellent cooling performance make it just as useful for everyday outings—great for keeping drinks and food cold on road trips, beach days, or weekend getaways.

Key Features:

● 52-Quart Capacity: Large enough for a full day on the water — no ice chest needed.
● Target Fish: Rockfish, Snapper, Striped Bass, Salmon, Walleye, Trout, Catfish
● Marine-Grade, Durable Vinyl: UV, mildew, and wear-resistant for long-lasting performance.
● 100% Leak Proof: Fish, ice, and beverages stay secure.
● Superior Insulation: 2" dense foam keeps contents cold for hours.
● Upright & Stable: Gusseted bottom maximizes storage and prevents tipping.
● Interior Waterproof Pocket: Ideal for fillets, drinks, or items you want separate.
● Convenient Storage: Exterior mesh compartments and Velcro pocket for tools and accessories.
● Built to Last: Non-corrosive YKK zipper and heavy-duty webbing handles.
● Easy Cleanup: Fully washable with built-in drain plug.

Dimensions: 32″L × 12″W × 18″H (dimensions may vary 2–4 inches due to high-density foam)

Durable, practical, and ready for your next adventure — the Fathom 3 keeps your catch cold and your gear organized.

The perfect everyday cooler bag!

I have a Fathom 5 on my 19ft mako for inshore/offshore fishing. I recently picked up a Fathom 3 after I saw one at Meric Spearfishing. It is the perfect solution for those days where you don't need a huge kill bag. We use it primarily for our drinks and food, but also take it out for kelp bass and rockfish. Same quality and ice life as my Fathom 5, but in a compact size. We even use it for beach days and as our camping cooler.

Super sturdy and just the right size.

This bag is amazing. Very waterproof and super sturdy. While I have not taken it out on the water (yet) it has made my trips from the grocery store way better :-)

Jess, we are happy that you love your bag for your groceries, and we look forward to seeing how much you love it when you get to take the bag out on the water. We make a great bag for all kind of great uses!

It is nice but not 2 inches of closed cell foam.

I like it but there are not 2 inches of closed cell foam as stated. There might be an inch on each side. 2 would have been great

Thank you, Katie, for the 5 star review. Sometimes when the bag arrives and is rolled up, the foam may be a little flat. Just let the bag sit outside for a day and warm up and the insulation should expand to the 2 inch thickness. Please reach out to us if you have any further questions at support@opahgear.com

The bags are great. The company's customer service needs a lot of work.

I recently purchase four bags from Opah gear, two Fathom 5 and two Fathom 3 to take on a moose hunt up to Canada in the fall. I ordered all of the bags at the same time. Only one Fathom 3 and one Fathom 5 bag arrived. The Fathom 5 bag was missing a storage bag, and was shipped in an oversize box, but since I had not ordered from the company previously I wrongly assumed a storage bag was NOT included. I called and they promised to ship the remaining two bags promptly. I received one bag, but was still missing one. I called again and finally got the last bag. The second Fathom 5 bag was shipped in a marked product specific box with a storage bag. I called to inquire why I had not received a storage bag and was told they might not have one, but they would email me. So far, no response. Their products are nicely made, but their customer service is poor.

Thank you, Steven, for your review of our product and customer service. We love that you think that our craftsmanship is good, and we aplogize for any short comings with our customer service. The order was written correctly, but our warehouse staff only packed one of each unit. We are glad you called us so that we could get your order corrected. I also checked our warehouses today for any additional storage bags for the Fathom 5, and we do not have any at this time. If I see an extra bag, I will make sure to send it to you. We will bring a better experience to you next time to make sure we match out great product.

Great quality

Just need a kill bag, wish the design of the bag was more on the simple side with the same quality. I don’t need the side pockets, mesh pockets, interior pocket. All that holds fish slime and snag possibilities. Overall the bag is great holds multiple 32 inch snakeheads no problem. No leaks the bag is A+
