Blueseventy Reaction Men's Wetsuit - $394.95

When it comes to gold medalists, world champions, and ironman victors, no one really touches the Washington-based Blueseventy. Just from its resume, it's easy to tell that its designs are purposeful and precise. However, its fan-favorite reception is really due to only including what you really need for race day. By this, we mean that you're going to find suits like the Reaction Wetsuit are focused on buoyancy and flexibility. Accordingly, you'll experience a minimized hydrodynamic profile, while your stroke and kick efficiency is maximized. To achieve this, Blueseventy produced the Reaction with a buoyancy ratio of 4-5-4. This means that the cell density of the suit's buoyancy sectors varies throughout its construction, from 4mm to 5mm. At the chest, you'll find two lateral panels of 4mm Yamamoto C38 neoprene. Additionally, the torso runs 5mm down 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 Reaction with the maximum thickness allowed under IFR, 5mm. Additionally, by placing 5mm panels along the back of the hips, you'll experience less body roll through your stroke, maximizing the efficiency of your movements. However, buoyancy amounts to nothing if your flexibility is inhibited by dense neoprene. - $394.95
