The Mares Instinct Camo Brown 55 5.5mm Open Cell Jacket is an open-cell neoprene open cell built specifically for freedivers and spearfishers. The 5.5mm 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 Mabul’s sandy hunting zones.

Suited for Malaysian Dive Sites
The Mares Instinct Camo Brown 55 5.5mm Open Cell Jacket performs reliably across Malaysia’s premier diving destinations. Whether you’re exploring Mabul’s sandy hunting zones, 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 Instinct Camo Brown 55 5.5mm Open Cell Jacket delivers on both – a suit that gets out of your way and keeps you comfortable on the breath-hold.

How does the Mares Instinct Camo Brown Jacket perform in cold water? Does it provide adequate thermal insulation? I’m planning to buy one for a diving trip in the north.

Thank you for your question about the Mares Instinct Camo Brown 55 5.5mm Open Cell Jacket. This jacket is designed to provide thermal insulation and comfort in cold water conditions. It features a 5.5mm neoprene construction and open-cell technology that traps warm air and helps to keep you insulated.

Is the jacket suitable for tropical climates? We have very hot and humid weather year-round in Singapore.

Thank you for reaching out to us about your concerns regarding the Mares Instinct Camo Brown 55 5.5mm Open Cell Jacket’s suitability for tropical climates. We understand that Singapore’s weather can be quite challenging, especially with the high humidity. While our jacket is designed to provide excellent thermal protection, it’s essential to note that it’s primarily intended for use in temperate climates.
