Care & Maintenance
- Rinse thoroughly after every dive – premium neoprene still degrades with salt exposure.
- Hang inside out to dry; this lets the seams breathe and prevents mildew.
- Lubricate the zip with silicone spray after every 5–10 dives.
- Store in a cool, dark place; premium neoprene is sensitive to UV and heat.

Elara Wong –
What is the difference between this 5mm wetsuit and the 7mm version? Is it suitable for cold water diving?
Imran Hanafiah –
Thank you for reaching out, Elara. The 5mm and 7mm versions of the Poseidon One Suit Sport share the same design, with the main difference being the thickness of the wetsuit. The 5mm version, like yours, is ideal for warmer waters, while the 7mm version is designed for colder waters. For cold water diving, we would recommend the 7mm version. However, it’s worth noting that the 5mm version can still be used for cold water, albeit with a bit less warmth. If you’re unsure, please let us know more about your diving needs, and we’ll be happy to provide more specific advice.

The 5mm Poseidon One Suit Sport has been my go-to wetsuit for tropical dives. The straight arm and leg openings make it easy to wear with boots and gloves. However, I wish it had a built-in weight system.

What is the recommended maintenance routine for this wetsuit? Can it be washed with a regular washing machine?
Imran Hanafiah –
Thank you for your review of the Poseidon One Suit Sport 5mm Female wetsuit. We recommend hosing it off with fresh water after each use to prevent any dirt or debris from being ground into the suit. For more thorough cleaning, we suggest hand washing it with mild soap and a soft-bristled brush. Avoid using a regular washing machine, as the agitation and spin cycle can damage the neoprene and compromise the suit’s flexibility. Regarding maintenance, we recommend storing the wetsuit in a dry place, away from direct sunlight, to prevent fading and degradation of the materials. If you have any further questions or concerns, please don’t hesitate to reach out to us.

This wetsuit is perfect for my diving needs. The material is durable and comfortable. However, I wish it came with a pair of booties to match.
Jacqueline Leong –
I’m not sure if I should upgrade to a 7mm wetsuit or stick with the 5mm. Can anyone share their experience with both versions?
Imran Hanafiah –
Thank you for your review of our Poseidon One Suit Sport 5mm Female wetsuit, Jacqueline. We’re happy to help you decide whether to upgrade to a 7mm wetsuit or stick with the 5mm one. Both our 5mm and 7mm women’s models are designed for versatility and comfort in various diving conditions. The 5mm version is ideal for tropical waters and warmer climates, while the 7mm is better suited for colder waters. If you frequently dive in cold waters or experience chilliness during dives, the 7mm might be a better choice. However, if you dive mainly in warmer waters, the 5mm should suffice. Would you like to share more about your diving experience or preferences?
