Blueseventy Helix Women's Wetsuit $699.95
All that you need.
It's rare that we find a wetsuit that knows exactly what its market needs and doesn't need. Not surprisingly, we're talking about the Blueseventy Helix Women's Wetsuit. We'll be blunt, you're not going to find any core-corrective or proprioception panels on the Helix. After all, if you're competing at the highest levels of triathlon, Blueseventy trusts that your form has been perfected along the way. Instead, the Helix places a focus on what really matters for elite racers -- buoyancy and flexibility. And along these lines, you'll find the thinnest arms, and one of the most advanced buoyancy ratios, on the market.
To achieve this, Blueseventy produced the Helix with a buoyancy ratio of 5-5-4. This means that the cell density of the suit's buoyancy sectors varies throughout its construction, from 5mm to 4mm. At the chest, you'll find two lateral panels of 5mm Yamamoto Aerodome neoprene. Additionally, this 5mm Aerodome has been extended down the torso to the lower legs. This maximizes buoyancy by keeping the hips high in the water, creating an efficient, 'downhill' swimming position. At the lower legs, where articulation is less frequent, you'll find that Blueseventy incorporated a 4mm Yamamoto C39 neoprene.
So, you might be asking yourself, why is any of this important? Well, just as curvy, sleek shapes minimize your drag coefficient on land, a wetsuit's level of buoyancy is the minimizing variable in the water. The supporting science behind this claim is fairly elementary -- water is around 1000 times denser than air, and it produces a potential drag coefficient 10 times that of air, as well. So, minimizing your body's submergence is vital to optimizing hydrodynamics. Accordingly, Blueseventy awarded the Helix with the maximum thickness allowed under IFR, 5mm.
However, buoyancy amounts to nothing if your flexibility is inhibited by dense neoprene. And, not surprisingly, this is where the Helix truly shines. In fact, you'll find that the Helix is the world's first wetsuit to feature 1mm neoprene in the arms and underarm gussets. In addition to this, Blueseventy carried this flexible construction throughout the Helix. The central split chest panel features a 3mm density, while the back panel uses a 2mm density. More impressively, the Helix features Blueseventy's Torsional Stretch Technology (TST), where the chest and back panels allow the arm and shoulder to 'disconnect' from the suit during your stroke. Essentially, this eliminates the suit's pulling up on the lowers during the locomotion of your stroke.
It's also worth noting that all of the aforementioned panels are constructed from SCS-coated Yamamoto C40 neoprene -- the most flexible in the business. And if you're wondering what SCS is, it's a hydrodynamic, silicone coating that provides an added level of buoyancy, while lowering the suit's coefficient of kinetic friction. Without entering into a physics lesson, the coefficient of kinetic friction is most simply described as the ratio of the force of friction between two bodies, and the force pressing them together. And in this case, the two bodies are your body and the water and friction occurs concurrently with their motions. So, in the real world, SCS acts almost like an accelerant as it reduces the friction between yourself and the water, ultimately requiring you to exert less force in order to gain more speed.
The Blueseventy Helix Women's Wetsuit is available in the color Black/blue/orange and in the sizes WL, WLA, WM, WML, WMS, WS, and WXS.

Good quality and fitting wetsuit
- Familiarity: I've put it through the wringer
I have raced in this wetsuit for the past 4 seasons. The reasons I like it are: 1) It is durable, even though the neoprene is very soft and flexible it does not tear easily like other brands I have tried and I give it a fair amount of abuse getting in and out of it quickly. 2) Mobility in the shoulders. I do not swim a lot in my wetsuit besides races so it's good to have a lot of flexibility in the shoulders 3) Overall fit, I am 5'5'' 116 athletic build and it fits me great, unlike a lot of women's suits that seem to be pair shaped, this one is good for athletes/swimmers. I find it fits a bit big compared to charts, I was able to still wear a small when I weighed 125-130lbs.
