The Zone3 AeroForce-X II is Zone3’s flagship triathlon suit, designed for athletes who are looking for maximum performance, aerodynamic efficiency and speed. Developed in collaboration with aerodynamics specialists Nopinz, it has been designed and tested with a clear objective: to reduce drag and help you save valuable seconds on the bike.
This is a race-focused trisuit, designed to perform across all three disciplines while putting particular emphasis on aerodynamics.
Aerodynamics is where the AeroForce-X II really stands out.
The suit combines five technical fabrics with Zone3’s Speedscalez™ surface technology, strategically positioned to optimise airflow around the body. The sleeves and leg panels are also designed with an aerodynamic cut to reduce turbulence and improve airflow when riding at speed.
The suit has been tested at different cycling speeds, including 30, 35, 40 and 45 km/h, making its aerodynamic concept relevant not only to professional athletes but also to ambitious age-group triathletes.
The AeroForce-X II is not simply an aero bike suit.
Its hydrophobic fabrics help minimise water absorption and reduce drag during the swim. This makes it particularly interesting for races where the swim is non-wetsuit legal, or for athletes who want a single suit capable of performing from the start of the race.
The suit has a highly aerodynamic, close-to-the-body fit. The fabric is designed to sit like a second skin, minimising movement and preventing excess material from catching the wind.
The result is a sleek, race-focused feel throughout the swim, bike and run.
The rear pockets are incorporated into the aerodynamic design, allowing you to carry essential nutrition without unnecessarily compromising airflow.
This is particularly useful for longer-distance racing, where gels and other nutrition need to remain easily accessible.
The AeroForce-X II uses a Cytech Italian-made triathlon-specific chamois, designed to provide support on the bike while remaining unobtrusive during the run.
The relatively minimalist construction is a deliberate choice: enough protection for the bike, without feeling bulky once you start running.
+ Exceptional aerodynamics
The AeroForce-X II is one of Zone3’s most performance-driven trisuits, with aerodynamics at the heart of its design.
+ Excellent all-round performance
It is designed for all three disciplines rather than being purely a cycling-focused aero suit.
+ Hydrophobic materials
The fabrics are designed to minimise water absorption and maintain performance during the swim.
+ Race-focused fit
The close fit helps keep the fabric stable and reduces unnecessary movement at high speed.
+ Attention to marginal gains
From the fabric selection to the sleeve and leg construction, pockets and seams, the suit is designed around the small details that can add up to meaningful time savings.
+ Suitable for a wide range of race distances
It can be used for sprint and Olympic-distance racing as well as 70.3 and long-course events.
No highly performance-oriented trisuit is perfect, and the AeroForce-X II involves a few compromises.
At 350 Swiss Francs in our site, the AeroForce-X II sits firmly in the premium end of the triathlon market.
For beginners or occasional triathletes, the additional investment may be difficult to justify. The aerodynamic gains are likely to be most valuable for athletes who are already well trained and able to maintain an efficient aerodynamic position on the bike.
The suit is designed to be very close-fitting. Getting the right size is therefore particularly important.
A suit that is too loose can compromise its aerodynamic benefits, while one that is too small may feel restrictive or uncomfortable.
The thin triathlon-specific chamois is a major advantage when running, but it can be a compromise for athletes spending several hours on the bike.
Independent testing has noted that some athletes may prefer a little more cushioning for very long-distance racing.
The suit’s closure system is not as convenient as some competing trisuits with more elaborate toilet-friendly or breakaway designs.
For long-distance racing, this is a relatively small issue, but it is worth considering if convenience is a high priority.
The AeroForce-X II is not trying to be the most relaxed or comfort-oriented trisuit on the market.
Its philosophy is simple:
prioritise speed, reduce drag and maximise performance.
Compared with a more traditional all-round trisuit, the AeroForce-X II places considerably more emphasis on aerodynamic optimisation. The trade-off is that the fit is more demanding and the minimalist chamois may not suit everyone for very long bike legs.
Within Zone3’s own range, the positioning is also quite clear: the AeroForce-X II is aimed at athletes looking for maximum aerodynamic performance, while models such as the Lava place greater emphasis on long-distance comfort and versatility.
The Zone3 AeroForce-X II is a trisuit for athletes who are serious about performance and want to extract every possible marginal gain from their equipment.
It is not necessarily the best choice if your number-one priority is maximum comfort over a very long day. But if your goal is to reduce aerodynamic drag, improve efficiency and save seconds, it is one of the most interesting high-end trisuits in Zone3’s range.
Bottom line: if your philosophy is “every second counts”, the AeroForce-X II makes a very convincing case. It is a highly specialised, premium racing trisuit where aerodynamics comes first, without forgetting the swim and run.
