The YETI Cayo Backpack is engineered for anglers who refuse to let water be the boss. When your pursuit of fish takes you into the harshest, wettest environments imaginable, this fully submersible fortress ensures your gear stays bone-dry from the boat deck to the saltwater flats. It’s built to carry a full day’s kit with uncompromising protection against the elements.

Why we like it

What truly sets the YETI Cayo Backpack apart is its sheer, uncompromising build quality that justifies its premium price. While other waterproof packs offer resistance, the Cayo offers absolute immunity to water with its submersible design. The combination of the burly ThickSkin Shell and the airtight HydraLok Zipper feels less like a backpack and more like a portable vault for your most valuable gear. Its an investment in peace of mind, allowing you to focus completely on fishing, knowing your camera, phone, and fly boxes are shielded by legendary YETI toughness.

Water Resistance/Waterproofing Features

The core of the Cayo’s protection is its 100% waterproof design. The main compartment is completely sealed from the elements by the HydraLok Zipper, the same robust, airtight zipper found on YETI’s soft coolers. This allows the pack to be fully submerged without any water intrusion. The exterior is made from the laminated, high-density nylon ThickSkin Shell, which not only repels water but also resists punctures and abrasion from hooks, rocks, and branches.

Carry System

The carry system is built for comfort during long treks to the water. It features ergonomic, padded shoulder straps with an air-mesh lining to promote airflow. A ventilated, hydrophobic back panel rests comfortably against your back and does not absorb water. For securing heavier loads and maintaining stability while casting or hiking, the pack includes both a removable, adjustable sternum strap and a simple, removable webbing waist belt.

Compatibility

The Cayo Backpack is designed to integrate seamlessly into the YETI ecosystem. The exterior HitchPoint Grid webbing is perfectly spaced for attaching the YETI SideKick Dry Gear Case, providing quick access to a smaller waterproof pouch. These lash points are also compatible with a wide range of MOLLE accessories, Zinger and nipper attachments, and other clip-on tools, allowing for extensive customization.
