7mm wetsuits

Our range of 7mm wetsuits and thicker semi-dry suits is for colder NZ water—and divers who like a little more warmth whatever the season. Compare different zip designs, men’s and women’s fits, and options for layering through winter.

What water temperature suits a 7mm wetsuit?

A 7mm one-piece is our go-to all-year North Island scuba option, with a hood and gloves added for winter water around 15°C. It’s also a summer choice if you prefer more insulation.

What does Tony wear for New Zealand scuba diving?

“A 7mm is my go-to. In winter I add a hood and gloves, and sometimes a vest underneath for colder, deeper dives. In summer, I love diving in the 7mm without the hood and gloves. I’ve never found a suit too warm.”

That’s why we don’t automatically steer everyone towards a thinner summer suit.

Should I choose a 7mm one-piece or a 5mm two-piece?

For scuba diving, Tony chooses a 7mm one-piece. For spearfishing and freediving, both Tony and Liz use a 5mm two-piece open-cell suit all year round.

We use the same general temperature guide for both setups. The overlapping jacket and long john add insulation around the torso, so a 5mm two-piece shouldn’t be compared directly with a 5mm one-piece.

What’s the difference between a wetsuit and a semi-dry?

A semi-dry is still a wetsuit. Its seals and zip are designed to reduce water flushing through the suit; it does not keep you dry like a drysuit.

Compare the fit, seals and zip arrangement alongside neoprene thickness.

How do I put together a winter setup?

Choose a close-fitting suit, then consider a suitable dive hood, gloves and any extra layers together. Adding layers should still leave you able to breathe and move comfortably.
