The Mares Apnea Instinct 30 3mm Lady Open Cell Jacket is an open-cell neoprene open cell built specifically for freedivers and spearfishers. The 3mm open-cell inner surface moulds to the body like a second skin, trapping a micro-layer of warm water that insulates effectively even during long, static breath-hold dives. Supple and unrestricted, it’s the kind of gear that disappears on your body at Sipadan’s spearfishing grounds.

Key Features

- Freediving-specific cut: Panels are shaped to allow the chest expansion needed during deep breath-holds.
Suited for Malaysian Dive Sites
The Mares Apnea Instinct 30 3mm Lady Open Cell Jacket performs reliably across Malaysia’s premier diving destinations. Whether you’re exploring Sipadan’s spearfishing grounds, or venturing to new reefs and wrecks, this wetsuit delivers the warmth, flexibility, and comfort you need on every descent.
Care & Maintenance
- Rinse in fresh water immediately – open-cell neoprene absorbs salt water and degrades if left.
- Never tumble dry; hang flat or lay on a towel to dry slowly.
- Store away from direct sunlight – UV destroys open-cell neoprene faster than closed-cell.
- Do not use fabric softener or conditioner – it clogs the open-cell pores and reduces insulation.
Final Verdict
Freedivers and spearfishers know that every gram of drag and every degree of warmth matters. The Mares Apnea Instinct 30 3mm Lady Open Cell Jacket delivers on both – a suit that gets out of your way and keeps you comfortable on the breath-hold.

Can anyone tell me if the material used for the Mares Apnea Instinct 30 3mm Lady Open Cell Jacket is eco-friendly?
Imran Hanafiah –
Thank you for reaching out about our Mares Apnea Instinct 30 3mm Lady Open Cell Jacket. We appreciate your interest in the eco-friendliness of our product. After researching the product, we found that Mares uses a combination of Neoprene and Synthetic Materials in their product, but Mares also includes several eco-friendly elements in its design. Their Open-Cell technology uses less material to achieve the same insulation performance. Additionally, Mares also has a partnership with environmental organization, and they collaborate to find ways to minimize waste and pollution in their production process. Please note, however, that materials used might not be 100% eco-friendly, so if this is a major concern for you, we would recommend reaching out to Mares directly to get the most current eco-friendly data.
