For warm-water spearfishing, the first question is how much insulation you need. A lightweight stinger suit provides a protective barrier against marine stingers with very little bulk. A neoprene wetsuit adds warmth. Where you dive, how long you stay in the water and how easily you feel the cold all affect the choice.
At Life Below, our two options are the Electric Blue DNA Stinger Suit and the Spearo DNA Tropical 2mm Wetsuit. This is how I think about choosing between them for northern Australian and South Pacific conditions.
What I wear through the tropical seasons
In tropical waters north of Mackay, and on my South Pacific trips, I generally reach for the stinger suit around October or November as the water warms. I tend to stay in it through to April or May, then move into the 2mm as the water cools. The stinger suit is almost an option for me all year round in the Pacific.
Between the two, that covers my usual northern-water diving through the year. It is a starting point from my own experience, rather than a fixed rule for every diver or every location. The changeover is about the conditions on the day, not a date on the calendar.
There are exceptions even in the warmer months. On a long day in blue water, I sometimes want the extra warmth of the 2mm. Further south, I generally find a 5mm necessary in the colder months. I would not choose a tropical 2mm simply because it is the warmest suit in this range if the trip calls for something warmer.
My in-between option: 2mm top with stinger bottoms
When the temperature sits between my usual choices, I sometimes wear just the 2mm wetsuit top with the stinger-suit bottoms. That gives me extra warmth around my torso while keeping the lighter Lycra coverage on my legs. It is a combination I use when I want more warmth than the full stinger suit, without moving into the full 2mm.
The difference between our two suits
| Feature | DNA Stinger Suit | DNA Tropical 2mm Wetsuit |
|---|---|---|
| Material | Stretchy Lycra fabric | 2mm Yamamoto #39 neoprene |
| Main reason to choose it | Stinger protection over covered skin when you do not need neoprene insulation | Added insulation for warm-water diving |
| Construction | Hooded top and high-waisted trousers reaching just below the nipples | Hooded jacket and high-waisted trousers reaching just below the nipples |
| Spearfishing features | Cushioned loading pad; reinforced knees and elbows; beavertail fastening | Cushioned loading pad; reinforced knees, elbows and seat; beavertail fastening |
The stinger suit packs down easily and can be put on dry. The wetsuit uses jersey-lined neoprene, with open-cell seals at the cuffs, ankles and hood. Both have a two-piece design and built-in hood, so the decision is largely about warmth, feel and the conditions you expect.
Both suits have trousers that rise to just below the nipples, creating a generous overlap beneath the top. On the stinger suit, this adds coverage around the torso for stinger protection. On the 2mm wetsuit, the overlapping neoprene adds insulation around the core, helping keep the area around your vital organs warm.
Choose for the whole day in the water
A quick swim and a long spearfishing session can call for different choices, even at the same location. Think about your planned time in the water, whether you will be spending long periods in blue water, and how you felt on your last comparable trip. If you usually get cold before the people you dive with, their suit choice may not be the right guide for you.
My seasonal pattern is useful for planning a tropical trip, but I still check local conditions and adjust. If you are travelling between regions or diving at a different time of year, ask someone who has been in the water there recently.
How does a stinger suit help protect you?
A stinger suit creates a fabric barrier between marine-stinger tentacles and the skin it covers. Lycra is useful because it is lightweight, stretchy and comfortable in warm water. It is not the only protective material: WorkSafe Queensland also recommends wetsuits, which add insulation.
Coverage, fit, fabric construction and openings all matter. Research comparing protective fabrics does not support treating every fabric or every exposure as equivalent. A snug, well-fitting suit helps maintain coverage, but exposed skin and openings remain vulnerable. UPF 50+ is a sun-protection rating, not a test of resistance to marine stings.
Stinger protection in northern Australian waters
Stinger protection is a central reason to wear the DNA Stinger Suit in northern Australian waters. Full-body Lycra suits offer a high degree of protection against marine stings, as recognised in Queensland’s diving and snorkelling guidance. Our hooded top, long sleeves and full-length, high-waisted trousers provide extensive coverage, with added overlap around the torso.
The tropical marine-stinger risk area is broader than the waters north of Mackay that I describe in my own seasonal routine. It includes:
- Tropical Queensland: generally north of Bundaberg, including the Mackay and Whitsunday region, Townsville, Cairns and Cape York. This is a broad guide, not a fixed southern boundary; WorkSafe Queensland notes that the range may extend further south.
- The Northern Territory coast: including the Top End. NT Health identifies October to the end of May as the period when venomous box jellyfish are more likely to be present.
- Northern Western Australia: including Broome and the Kimberley, and south to the Exmouth/Ningaloo region. See Surf Life Saving Queensland’s species guidance and the WA Museum’s record of Irukandji stings around northern Ningaloo and Exmouth Gulf.
In tropical Queensland, the higher-risk season is usually November to May, although marine stingers can occur year-round. My change from Lycra to neoprene is a warmth decision, not a signal that stinger risk has ended.
A suit protects the skin it covers; exposed areas and openings still need consideration. No suit guarantees protection from every sting. Follow local warnings, beach closures and advice for your specific location, regardless of the month.
UPF 50+ sun protection in both suits
Both the DNA Stinger Suit and DNA Tropical 2mm Wetsuit provide UPF 50+ sun protection on covered skin. Their built-in hoods, long sleeves and full-length, high-waisted trousers provide extensive coverage. That applies to the areas covered when I mix the 2mm top with stinger-suit bottoms too. Use sunscreen and other sun protection on exposed skin; the rating does not mean complete protection for every part of your body.
Get the fit right as well
Whichever suit you choose, compare your chest and waist body measurements, height and weight with its own size guide. Chest and waist ranges are body circumferences in centimetres, showing the recommended fit that the stretch of each size accommodates. Both suits stretch, and body shape can change the best size for you. If you are between sizes or unsure, our recommendation is to size up.
