Wetsuit Thickness Guide
Choose the right thickness for your water temperature and activity.
Recommended Thickness by Water Temp
| Water Temp (°C/°F) | Wetsuit Thickness | Best For |
|---|---|---|
| Below 12°C / 54°F | 5/4mm or 6/5mm + hood & boots | Ice diving, cold-water surfing |
| 12–17°C / 54–63°F | 4/3mm or 5/4mm | Surfing, diving in cool regions |
| 17–22°C / 63–72°F | 3/2mm or springsuit | Moderate climates, long sessions |
| 22–27°C / 72–81°F | 2mm or shorty | Warm water, snorkeling, triathlons |
| Above 27°C / 81°F | Rashguard or none | Tropical waters |
Flexibility vs. Warmth Trade-Off
► Thicker (5mm+): Warmer but less flexible (ideal for cold water).
► Thinner (2–3mm): More flexible but less insulation.
Activity-Specific Tips
► Surfing: Prioritize arm flexibility (e.g., 3/2mm for 18°C).
► Diving: Opt for sealed seams in colder water.
► Triathlons: Slim-fit 2–3mm for speed + warmth.
► Note: Wind, sun exposure, and personal tolerance affect warmth needs. Adjust accordingly!
