How to Choose the Right Mares Wetsuit Size
A wetsuit should feel close-fitting without restricting breathing or movement. A good fit helps reduce water flushing, improves thermal protection and keeps the suit comfortable throughout the dive.
- Measure your height, chest, waist and hips.
- Match your measurements as closely as possible to the chart below.
- If your measurements sit across two sizes, prioritise the fit through the torso and chest.
- Remember that a wetsuit should feel snug on land and normally relax slightly once in the water.
Please note: Mares sizing is a guide, and not every size is available in every wetsuit model. The source guide also advises checking the suit fit properly before first use.

Why Buy a Mares Wetsuit?
Mares is one of the best-known names in diving, trusted by recreational divers, club divers and travelling divers alike. A Mares wetsuit is designed to deliver reliable comfort, flexibility and thermal protection across a wide range of water temperatures.
Whether you need a compact travel suit for holiday diving or a thicker wetsuit for longer sessions in cooler water, Mares offers options for different conditions and experience levels.
What Thickness of Wetsuit Do You Need?
The right thickness depends on where you dive, how long you stay in the water and how cold you personally feel.
- Up to 3mm: best for warm-water diving, snorkelling, pool training and holidays in tropical conditions.
- 5mm and above: better suited to cooler water, longer dives and divers who need more thermal protection.
Mares Wetsuit Fit Tips
- The suit should sit close to the body with no major loose areas around the lower back, underarms or behind the knees.
- You should be able to lift your arms and bend comfortably without excessive restriction.
- A small amount of effort getting the wetsuit on is normal.
- If the zip strains heavily or breathing feels restricted, try the next size up.
Frequently Asked Questions
Are Mares wetsuits true to size?
Mares wetsuits generally follow the size chart closely, but fit can vary slightly depending on suit thickness and design. Always compare your body measurements to the chart before ordering.
Should a Mares wetsuit feel tight?
Yes, a wetsuit should feel snug. A close fit helps reduce water movement inside the suit, which improves warmth and comfort during the dive.
What if I am between two sizes?
If you are between sizes, use your chest and torso fit as the main priority. A wetsuit that is too loose will usually feel colder in the water than one that is slightly more fitted.
Can I use this guide for all Mares wetsuits?
This chart is a useful reference point, but availability and exact fit can vary by model. The source guide also notes that not all listed sizes are available in every wetsuit.
