Best Triathlon Wetsuits: A Complete Buying Guide
A good wetsuit is one of the most important investments you’ll make as a triathlete. It provides buoyancy, warmth, and can genuinely improve your swim speed. Whether you’re preparing for your first open water event or upgrading from an old suit, this guide covers everything you need to know.
Why You Need a Triathlon-Specific Wetsuit
Triathlon wetsuits differ from surfing or diving wetsuits in several key ways. They’re designed for forward swimming motion with flexible shoulder panels, and they use varying neoprene thickness to maximise buoyancy where you need it most — typically 5mm in the torso and 2-3mm in the arms and shoulders.
What to Look For
- Fit: Snug but not restrictive. You should be able to rotate your arms freely without the suit riding up
- Neoprene quality: Yamamoto neoprene (Japanese-made) is considered the gold standard for flexibility and buoyancy
- Panel construction: More panels generally means a better, more tailored fit
- Zip: Back zip is standard and easiest for quick transitions. Some premium suits offer front zip for comfort
- Coating: SCS (Super Composite Skin) coating reduces drag through the water
Recommended Wetsuits
These are our top picks for triathlon wetsuits at different price points:
Zone3 Advance Wetsuit — Best for Beginners
The Zone3 Advance is one of the best entry-level triathlon wetsuits available. It uses Yamamoto #38 neoprene with SCS coating, offering excellent buoyancy and flexibility at a price that won’t break the bank. The fit is forgiving, making it ideal for first-time open water swimmers. Expect to pay around £150-200.
Orca Athlex Float — Best Mid-Range
The Orca Athlex Float is designed specifically for swimmers who want extra buoyancy in the legs and hips. The 5mm Yamamoto neoprene core panels keep you high in the water, while the arms use thinner, more flexible material. A brilliant choice for the improving triathlete. Around £250-350.
Blueseventy Helix — Best Premium Choice
If budget allows, the Blueseventy Helix is a race-level suit that delivers outstanding speed and comfort. The Yamamoto #40 neoprene is incredibly flexible, and the multi-panel design fits like a second skin. This is the kind of suit that genuinely makes you faster. Expect to pay £400+.
Sizing and Fit Tips
Always refer to the manufacturer’s size chart — sizes vary significantly between brands. When trying on a wetsuit, it should feel tight but you should be able to breathe comfortably and swing your arms in a full circle. A suit that’s too loose will let water flush through and negate the thermal benefit.
Care and Maintenance
- Rinse in fresh water after every swim
- Hang dry inside out, away from direct sunlight
- Never use a standard hanger — use a wide-shouldered wetsuit hanger or fold over a rail
- Apply Body Glide or similar lubricant to neck and wrists to prevent chafing
A well-maintained wetsuit should last 3-5 seasons of regular use. Consider starting with a mid-range suit if you’re new to the sport, and upgrading once you know your preferences.
