Unlike most hallmark wetsuits, the Blueseventy Helix Wetsuit doesn't bother itself with all of the weight and complexity that's derivative of hyper-corrective accoutrements. Instead, its focus is devoted to buoyancy, thin constructions, and most importantly, flexibility. Simply put, Blueseventy created the Helix for advanced swimmers, not to make the moderate exceptional. 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 d...
