The Mares Explorer 70 7mm Open Cell Jacket is an open-cell neoprene open cell built specifically for freedivers and spearfishers. The 7mm 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 Perhentian’s reef flats.

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 Explorer 70 7mm Open Cell Jacket performs reliably across Malaysia’s premier diving destinations. Whether you’re exploring Perhentian’s reef flats, 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 Explorer 70 7mm Open Cell Jacket delivers on both – a suit that gets out of your way and keeps you comfortable on the breath-hold.

This jacket is amazing! Is there a variant with a zipper closure? I’m not a huge fan of the Velcro.

Thank you for taking the time to share your review of the Mares Explorer 70 7mm Open Cell Jacket! We’re thrilled to hear that the overall design is amazing for you. Unfortunately, the standard jacket does not come with a zipper closure. We can consider your suggestion for a future variant, though. For now, our recommendation would be to use an aftermarket zipper conversion kit if this is something that prevents you from fully utilizing this product.
