3mm wetsuits

Our 3mm wetsuits are for warm-water adventures, from tropical scuba trips to snorkelling over the reef. Choose full-length coverage for a little warmth and protection without the bulk of a thicker suit.

What water temperature suits a 3mm wetsuit?

Over 25°C is our general guide for choosing a 3mm wetsuit. That’s what we wear on tropical dive trips, with a full-length suit giving us coverage for those moments when we get a little too close to the reef. Keeping clear of the coral is still the aim—for your sake and its.

Everyone feels the cold differently. Our temperature guides are a starting point, not a personalised recommendation. Fit, suit construction, time in the water and repeated dives all influence what you’ll need.

What do Tony and Liz wear in the tropics?

Our go-to is a full-length 3mm suit. It gives us coverage as well as insulation, so warmth isn’t the only reason we pack one.

Tony’s warm-water approach is a little more relaxed: “Above 28°C, board shorts and a rash shirt are all I need—but I do carry a bit of extra protection!”

Should I choose a 3mm or a thicker wetsuit?

For tropical diving over 25°C, we start with a 3mm. For New Zealand diving, compare our 7mm one-piece wetsuits and 5mm two-piece suits. A two-piece suit overlaps around your torso, so thickness alone doesn’t tell the whole story.

How should my wetsuit fit?

Choose a close fit without restricted breathing or movement. Use your measurements and the individual suit’s sizing guide.
