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 fi...
