Grundens Neptune Jacket

Yes, the Neptune jacket is designed with a heavy-duty, water-repellent finish to protect against harsh rain and ocean spray. While the 100% cotton duck canvas is highly water-resistant, it is not a fully seam-sealed rain slicker. It is best suited for damp maritime conditions rather than torrential, submersion-level downpours.

To clean the canvas jacket, you should hand wash it in cold water with a mild detergent and strictly avoid using bleach. Do not dry clean the garment, as harsh chemical solvents can destroy the cotton's natural oils and water-repellent properties. It should be line-dried to prevent the material from shrinking.

While it offers excellent wind resistance, the Neptune is primarily a shell jacket and does not feature thick internal insulation. It is intended to be layered over a sweatshirt or fleece during cold maritime winters. This design allows commercial fishermen and outdoor workers to adjust their warmth levels freely.

The Neptune utilizes heavy-duty YKK brass zippers and snap-closure storm flaps to ensure water stays out during demanding tasks. It also features neoprene cuffs to seal the wrists tightly against the elements. These rugged components are chosen specifically to withstand harsh, corrosive saltwater environments.
