Cressi Posidonia Wetsuit Jacket 5mm
The Posidonia jacket provides the upper half of a two-piece spearfishing wetsuit. It combines 5 mm neoprene with a flexible camouflage outer and an open-cell interior.
Features and Benefits
- Open-cell interior: The unlined inner neoprene sits directly against the skin, helping the suit seal closely and limit water movement. A compatible dressing lubricant helps the surface slide into place without pulling on it.
- Flexible panels: Stretch in the material helps the suit follow shoulder, hip and knee movement. This supports reaching equipment and swimming when the suit is correctly sized.
- Water control at the openings: Smooth hood and wrist seals. A close seal reduces the repeated replacement of warmed water with colder water. Check that the seals sit flat and overlap properly with the rest of your exposure gear.
- Reinforcement: Chest loading reinforcement. These panels help resist everyday rubbing at contact points without requiring the whole suit to use the same tougher outer material.
- Loading pad: The chest pad provides a reinforced contact area when loading a speargun. Position the suit and pad correctly before loading; it does not replace correct technique.
- Outer finish: Stretch cryptic camouflage. The finish distinguishes this version within the range; choose the suit by its construction, coverage and fit as well as its appearance.

Fit and Sizing
Compare your chest, waist, hips and height with the model’s size guide. The suit should sit closely without restricting breathing or shoulder movement. Settle the panels into place and check for excessive gaps or folds before deciding on a size. This listing is for the jacket only; choose the matching component separately and check the overlap and fit together. Match the thickness and coverage to the water conditions, activity and your own comfort. Warmth depends on fit, exposure time and the rest of your exposure gear.
More About This Model
The jacket boasts a 5mm thickness. The exterior is highly elasticised camouflage, while the interior is split neoprene. The cut is derived from the Tracina model, which is now widely regarded as a highly wearable option. The new chest reinforcement provides a strong grip when loading rifles, while the knee reinforcement offers additional protection against chafing without compromising the jacket’s elasticity.

Gear Care and Washing
Dive Gear Australia recommends Cressi Neoclean Wetsuit Wash or Revivex Wetsuit Shampoo for compatible neoprene. Regular cleaning helps remove salt, chlorine and everyday residue and, together with thorough drying and proper storage, helps extend your gear’s life. Use the label dilution and follow this product’s care instructions.
For dressing, use a lubricant made for open-cell wetsuits, mixed as its instructions require. Work the suit into place with flat hands, keeping fingernails and jewellery away from the unlined surface. Avoid ordinary shampoo or conditioner as a dressing lubricant.
After every use, rinse the suit inside and out in cool fresh water to remove salt, chlorine, sand and other residue. Gently hand wash when needed using a wetsuit cleaner suitable for the material, following the cleaner’s dilution instructions and the garment care label. Rinse thoroughly after washing.
Let both sides dry completely in the shade with good airflow. Support the suit on a broad wetsuit hanger, or drape it over a wide support to avoid stretching the shoulders. Store clean and dry in a cool place away from direct sunlight, heaters, hot cars and sharp folds.
Handle smooth seals and inner surfaces gently. Avoid scraping, scrubbing, fingernails and jewellery, and do not stretch a seal by pulling on a small section of it.
Do not machine wash, tumble dry, iron, bleach or use solvents. Follow the supplied care instructions for this suit and its zip before using any cleaning or maintenance product.
