blueseventy Fusion Wetsuit Review 2026: Best Beginner Triathlon Wetsuit?
What to Look For
A triathlon wetsuit is one of the most impactful pieces of kit you will buy — adding buoyancy, reducing drag, and helping you stay warm in open water. For beginners and intermediate triathletes seeking a reliable, well-constructed suit that performs across sprint, Olympic, and 70.3 distances, the blueseventy Fusion has been a trusted recommendation for over a decade. Here is how it compares to the alternatives.
Key Features to Consider
- Buoyancy panels — 5mm neoprene across the front of the legs and torso provides significant lift, keeping your hips and legs high for a flatter body position and reduced drag.
- Shoulder flexibility — 2mm neoprene across the shoulder and upper arm keeps your swim stroke unrestricted — critical for maintaining technique over longer swims.
- SCS nano coating — The outer skin coating reduces drag through the water, helping you hold a faster pace for the same effort output.
- Competition approval — The Fusion is IRONMAN and USAT approved, making it legal for all mainstream triathlon formats in water temperatures below 24.6°C.
Our Top Picks
Best for Men: blueseventy Fusion Men’s Triathlon Wetsuit
The men’s Fusion is one of the best-value full-sleeve wetsuits available for triathlon. The combination of 5mm buoyancy panels and 2mm shoulder flexibility delivers genuine performance across all distances. It fits true to size for most builds — blueseventy provides a detailed sizing chart on their website that factors in both height and weight. For anyone completing their first triathlon or upgrading from a surf wetsuit, the Fusion is the clear starting recommendation.
Best for Women: blueseventy Fusion Women’s Triathlon Wetsuit
The women’s Fusion is cut specifically for female athletes, with contoured panelling across the core and adjusted neoprene thickness to suit a female swimmer’s body position in water. The suit is Ironman and USAT approved, and sits at the same accessible price point as the men’s version. Experienced pool swimmers transitioning to open water will appreciate the additional buoyancy at the hips without feeling restricted through the shoulders during their catch.
Best Step-Up: Zone3 Aspire Wetsuit
If your budget stretches a little further, the Zone3 Aspire is the go-to mid-range option from a British brand well regarded throughout UK triathlon. It uses Yamamoto neoprene with SCS coating across the full suit, and the 5mm/3mm/2mm zoned construction provides a more sophisticated buoyancy-flexibility balance than the Fusion. The Aspire has earned best-buy awards from 220 Triathlon and Triathlete Europe and represents a meaningful performance step from the Fusion without moving into premium territory.
Buying Tips
- Always use the brand’s own sizing chart rather than your clothing size — wetsuit sizing is not standardised. Height and weight are the two most important measurements; chest and hip measurements help if you are between sizes.
- If you are between sizes, go smaller — a wetsuit that is too loose will take on water and create drag. It should feel like a firm hug without restricting your breathing when you exhale fully.
- Buy your wetsuit at least four weeks before your first race so you can complete two or three practice swims in it before race day and resolve any fit issues in advance.
Care and Maintenance
Always rinse your wetsuit in cold fresh water immediately after use and hang it inside-out in the shade to dry. Never leave it folded or compressed in a bag for extended periods, avoid direct sunlight and heat sources, and store it flat or loosely rolled — never on a wire hanger, which can distort the neck seal over time.
