Many beginners buy the wrong wetsuit simply because they do not understand how coverage affects body heat.
1. What Is a Shorty Wetsuit?
A shorty wetsuit has short sleeves and short legs, usually 2mm–3mm thick.
Best for:
-
Water temperatures above 22°C / 72°F
-
Swimming, snorkeling, warm-water surfing
-
Maximum freedom of movement
Shorties are lightweight, flexible, and easy to put on — but they provide limited thermal protection.
2. What Is a Full Wetsuit?
A full wetsuit covers your arms and legs completely and ranges from 3mm to 5mm or thicker.
Best for:
-
Water temperatures below 22°C / 72°F
-
Scuba diving, spring and autumn surfing
-
Long sessions in cooler conditions
Full wetsuits trap more warm water and dramatically reduce heat loss.
3. How Water Temperature Affects Your Choice
| Water Temperature | Recommended Suit |
|---|---|
| 26°C+ / 79°F+ | Shorty or 2mm full suit |
| 20–25°C / 68–77°F | 3mm full wetsuit |
| 15–19°C / 59–66°F | 5mm full wetsuit |
| Below 15°C / 59°F | 5mm+ with hood, gloves, boots |
4. Comfort vs Protection
Shorties feel free and light, but once the temperature drops, body heat disappears fast.
A full wetsuit may feel warmer on land — but in the water, it makes all the difference.
Final Thoughts
If you only dive or surf in tropical waters, a shorty is enough.
If you plan to explore cooler oceans, lakes, or longer sessions, a full wetsuit is essential.
Choosing the right coverage means staying in the water longer — and enjoying every minute of it.
