Full details

The Grundens Neptune 319 Jacket is a professional-grade outer layer designed specifically for commercial fishermen and outdoor enthusiasts who require uncompromising waterproof protection in harsh maritime environments.

FAQs

Is the Neptune 319 Jacket machine washable?

It is generally recommended to hand wash or rinse with fresh water and mild soap to preserve the integrity of the waterproof PU coating.

Does this jacket come with a hood?

The Neptune 319 design focuses on the jacket structure; check specific product variants if a hooded configuration is required for your specific work environment.

Can I use this for recreational fishing?

Absolutely. While designed for commercial use, its durability and waterproof features make it an excellent choice for any recreational angler facing wet conditions.

How should I store this jacket?

Store in a cool, dry place. Avoid folding it tightly for long periods; hanging it on a sturdy hanger is best to prevent permanent creases in the PU material.

Does the jacket provide insulation?

No, this is a shell layer. It is designed to be waterproof and windproof, allowing you to layer underneath with fleece or thermal wear depending on the temperature.

Troubleshooting

Water penetrating the jacket surface

Check the PU coating for punctures or cuts. Minor tears can often be repaired with a dedicated PU patch kit.

Stiffness or build-up on the exterior

Salt and debris can cause the material to feel stiff. Clean with fresh water and a mild soap-free detergent, then hang to dry properly.

Adjustment points feel loose

Inspect the drawstrings and toggles for trapped debris. Clean the hardware and ensure the cinch locks are fully engaging.

Pros and Cons

  • Balanced weight for all-day comfort
  • Excellent durability against harsh marine environments

Setup, Compatibility & Care

To ensure the longevity of your Neptune 319, it is important to follow proper maintenance protocols. After use in salt water, rinse the jacket thoroughly with fresh, cool water to prevent salt buildup, which can degrade the PU material over time. Always air dry the garment in a well-ventilated area away from direct heat sources or prolonged, intense sunlight, as extreme heat can compromise the waterproofing. When sizing, remember this is designed as an outer layer; if you plan to wear heavy mid-layers underneath, ensure you have sufficient room in the chest and shoulders for a full range of movement.
