5mm wetsuits

Our 5mm two-piece wetsuits are for freediving and spearfishing, with jackets, long johns and complete bundles. The overlapping layers around your torso make these a different proposition from a 5mm one-piece suit.

What water temperature suits a 5mm two-piece wetsuit?

We use the same general temperature guide for a 5mm two-piece as a 7mm one-piece: year-round North Island diving, including winter water around 15°C with suitable coverage.

The jacket and long john overlap through your torso, adding insulation where the two pieces meet. Check the individual suit’s construction, as some long johns use thinner neoprene through the upper body to reduce bulk.

What do Tony and Liz wear for spearfishing and freediving?

Both Tony and Liz wear a 5mm two-piece open-cell suit all year round for spearfishing and freediving. It’s our go-to setup through the New Zealand summer and winter.

Open-cell or lined interior?

An open-cell interior sits closely against your skin and needs suitable wetsuit lubricant and careful handling when dressing. Avoid pulling at it with your fingernails.

A lined interior is easier to pull on and less delicate to handle. It’s a practical alternative if you prefer getting dressed without lubricant.

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

For spearfishing and freediving, we choose a 5mm two-piece open-cell suit. For scuba, Tony’s go-to is a 7mm one-piece.

Choose around the activity, fit and construction rather than treating the thickness labels as a direct warmth comparison. Where a bundle offers separate sizes, you can also match the jacket and long john to your proportions.
