Complete Buying Guide
Looking to buy a new wetsuit for surfing, wakeboarding, or kitesurfing? The right wetsuit will keep you warm, flexible, and comfortable—even in the coldest Canadian waters. In this article, we’ll break down exactly how to choose a wetsuit based on water temperature, thickness, sport, and fit.
1. Wetsuit Thickness Guide by Water Temperature
Wetsuits are made for different temperature ranges. Here’s a quick reference chart:
| Water Temp (°C / °F) | Recommended Thickness | Wetsuit Style |
|---|---|---|
| 22°C+ / 72°F+ | 1–2mm | Springsuit / Shorty |
| 17–22°C / 63–72°F | 3/2mm | Full Wetsuit |
| 12–17°C / 54–63°F | 4/3mm | Sealed Full Wetsuit |
| 6–12°C / 43–54°F | 5/4mm or 5/3mm | Hooded Wetsuit with boots & gloves |
| <6°C / <43°F | 6/5/4mm+ | Full wetsuit with hood, boots & gloves |
Pro Tip: Always check water temperature before choosing your wetsuit—not just the air temp!
2. What Do Wetsuit Numbers Mean?
Example: A 4/3mm wetsuit means:
- 4mm neoprene on the chest and back for warmth
- 3mm neoprene on arms and legs for flexibility
More thickness = more warmth, but slightly less mobility. Choose based on your activity and comfort zone.
3. Wetsuit Entry Styles: Back Zip vs Chest Zip vs No Zip
- Back Zip: Easy to get on/off. Great for beginners. Less stretch, more water entry (flushing).
- Chest Zip: More stretch, warmer, better seal. Ideal for cold water and surfing.
- Zip-Free: Maximum stretch and lightweight feel. Slightly harder to put on.
4. How Should a Wetsuit Fit?
A proper wetsuit should fit like a second skin:
- No loose fabric or baggy areas
- No gaps in the back or underarms
- Comfortable arm and leg movement
Too loose? Water will get in. Too tight? It’ll restrict movement. Most wetsuits feel snug when dry—they loosen slightly when wet.
5. Pick the Right Wetsuit for Your Sport
- Surfing: Prioritize stretch and paddle flexibility
- Wakeboarding: Choose durability and fast-dry lining
- Kitesurfing/Windsurfing: Look for wind-blocking insulation
- Paddleboarding (SUP): Go for lightweight and mobility and not to thick !
