It doesn't get any thinner.

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 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 Wetsuit is available in the color Black/blue/orange and in four sizes from X-Small to X-Large. Please note that Blueseventy is also offering this wetsuit in SM, SMT, ML, and MT sizing options.

Great Company

This is a reliable company with outstanding service and integrity. Huge respect for their "customer first" mindset during the shopping experience and transactions. Looking forward to getting my new wetsuit into the water!

Favorite Wet Suit

  • Familiarity: I've used it several times
  • Fit: True to size

Heard good things about this one and had to try it out. Fits true to size and is leagues better than any sleeveless wet suit I've ever owned. Going with the full wet suit helped my mile swim time by a couple minutes and crushed my old PR's. Great buy
