The Hurricane Cat 5 Wetsuit incorporates every feature and technological advantage from the lower numbered entries in the line under the umbrella of one, final upgrade. The base material used throughout is Yamamoto's 39 Cell Nano SCS Super Composite Skin neoprene, which nets substantial gains in buoyancy even over the considerably advanced 38 Cell neoprene in the Cat 3 Wetsuit. Combined with the other Hurricane features, this buoyancy makes the water work for you. Some of the Cat 5's most water taming inclusions are the elevation panels situated around the torso to further complement the gains in buoyancy made by the 39 Cell neoprene. These panels also help maintain the most efficient body position for swimming by pulling you up at the obliques, chest, and core. The Cat 5 also sees a return of the Cat 3's Alpha Catch Panels on the forearms. These little grabbers catch water during your stroke and release it at the end to actually pull you through the water. Of course, the technology that makes the Cats 1 and 2 fullsuits such great values are also included here, with our favorite being the five panel 360 Core Stabilization System. This system provides compressive support to your key muscle groups to reduce long term fatigue, improve blood circulation, and further promote optimal posture in the water. It also adds yet another additional element of buoyancy so you can focus on moving forward, not staying afloat. Like its younger siblings, the Cat 5's shoulders incorporate TYR's Free R. O. M. Range of Motion Zone design, which eliminates restriction in the shoulder for long reaching swimming motions. The wrist and ankle cuffs are also the same as the rest of TYR's fullsuits. The wrist cuffs are designed to stretch in multiple directions, so they're unrestrictive but still prevent flushing throughout your stroke. When you get to T1, the ankle cuffs are tapered to catch your shins, allowing the wetsuit to peel inside out for quick removal.
