The Mares Explorer Camo Black 30 3mm 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 Perhentian’s reef flats.

Suited for Malaysian Dive Sites
The Mares Explorer Camo Black 30 3mm 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 Camo Black 30 3mm Open Cell Jacket delivers on both – a suit that gets out of your way and keeps you comfortable on the breath-hold.




Lian Cheong –
I recently purchased the Mares Explorer Camo Black 30 3mm Open Cell Jacket and I must say it’s been a game-changer for my diving adventures. The camouflage design is perfect for concealing myself in murky waters, and the 3mm thickness provides ample comfort and flexibility. I’ve worn it on multiple dives and it’s held up remarkably well. The only reason I wouldn’t give it 5 stars is that the seams could be slightly more secure, but overall, I’m extremely satisfied with this purchase.

The Mares Explorer Camo Black 30 3mm Open Cell Jacket is a solid choice for any scuba diver, but the 3mm thickness may not provide enough warmth for colder water dives. I wish there were more color options available, but overall, it’s a great purchase.
