• Optimizing the maximum 5mm thickness allowed under the International Federation Rules, and incorporating 39 cell rubber - the most buoyant on the market due to the cell density (spec gravity=.13). Maximum buoyancy means less body in the water therefore less wetted surface area, and a faster overall speed through the water. Water is 1000 times denser than air, and has a drag coefficient 10 times greater than air. Buoyancy is the ultimate component of speed.
  

• 2XU Comp1 wetsuit utilises SCS. The underwater coefficient of dynamic friction of the SCS is 0.026 in comparison to 4.0 of regular neoprene. Less friction = more speed.
  

• 2XU have engineered the Comp1 wetsuit with the optimum chest/hip buoyancy balance. Synchronising hip and chest buoyancy through the front panel cut Without this formula hip or chest submersion can occur throwing out your level body position and your stroke, bringing into play both inefficient technique and the usage of untrained muscles , bringing on quicker fatigue.
  

• The hydrodynamic flow over the front of the wetsuit is interrupted by seams, so 2XU have a one piece design from the neck to the knee to reduce drag and increase speed through the water.
  

• Industry first Roll Bar region improves the buoyancy in the core of the wetsuit. Better body position is delivered through maintained buoyancy when the body rolls off the front panel. This ultimately maintains higher body position (speed in water) and derives power from better positioned hips - enhancing the pull phase of the stroke
  

• The main factor for underarm material selection is flexibility. The underarm is a key panel which dictates the degree of shoulder and arm movement , releasing the swimming stroke action, allowing a complete extension along the latissimus dorsi. Both the neoprene and inner lining materials have been selected for maximum flexibility.
  

• With 520% elongation - 4 way stretch - 2mm neoprene. This is in turn complemented by the most flexible nylon lining available.
  

• The advanced material and construction of the 2XU underarm panel delivers maximum flexibility to enable the greatestrange of arm extension, rotation, abduction and adduction. In short a full unrestricted range of arm movement.
  

• The lower legs have a reduced 3mm panel structure to help with the run up the beach, and to remove the wetsuit with more ease.
  

• Adjustable length leg to customize fit for your kicking style. Trim the leg length back to reduce buoyancy and lower your feet for more kick power, or save your legs for the bike and run with a full flotation suit to the ankle.
  

• Quick release leg cut for faster suit removal
  

• Fundamental panels many other wetsuit brands underestimate. 2XU have engineered a back panel structure which is strong enough to contain the rigid zip, withstanding the punishment of constant use, but more importantly flexible enough to interact with the underarm panel, and allow the zip to float with body movement. This is achieved by the one piece floating zip panel, no seams so less restriction.
  

• The floating zip back panel enhances flexibility of our back panel which allows the zip (by construct non stretch) to move in partnership with the body, especially during the recovery and catch phase of the stroke – when your arm moves through the largest motion from beside your hip to entering the water in front of you, requiring the wetsuit to stretch along your back and shoulder.
  

• The 2XU floating back panel also has the advantage of contributing to better expansion of the chest cavity, therefore reducing restriction to the breathing motion. The less flexible 4mm front flotation panel is complemented by the hyper flexible 2mm underarm panel and 3mm back panels to promote core expansion and breathing.
  

• These two panels are all about maximising buoyancy, while having an anatomical fitting shape so water does not gather in this region. An ill fitted suit will allow the back up of water and increase in weight.
  

• We have used 39 cell neoprene for optimum buoyancy, and have also utilised a backing which will hold its shape and support in a region where most of the power in the stroke can come from.
  

• In utilizing materials which compress the muscles in the buttock and higher leg greater muscle stability reduces fatigue and allows the muscle to be primed for greater power output.
  

• Crotch panel also utilizes slightly thinner thickness to enhance the run up the beach by allowing more flexibility without sacrificing the suits buoyancy.
  

• Yet another 2XU benefit. One seamless panel running from the neck to the wrist. No seams translates to more flexibility through the shoulder and elbow region.
  

• Utilising hyper flexible yet buoyant 2mm 39 cell rubber with the most flexible nylon lining on the market the 2XU shoulder allows for unrestricted movement.
  

• The rough capsule texture on the anterior forearm (ratherthan the smooth SCS coating we have on the other panels) grips the water and enhances the power of your catch with a better purchase of the water. This mesh panel anchors the arm so the body can effectively flow through and past the planted forearm, enhancing your ability to pull yourself through the water.
  

• The neckline must balance tension perfectly to minimize both water intake and chaffing.

• This neckline solution is completed with an adjustable fastening collar system, allowing you to personalize the fit and maintain the perfect tension.
  

• Seamless front construction so less drag.
  

• 2XU seamless neck panel, for greater flexibility and comfort (chaf-free). This neckline solution is completed with an adjustable fastening collar system, allowing you to personalize the fit and maintain the perfect tension.
  

• The 2XU zip is manufactured from reliable light andstrong material, positioned behind the back panel lapels to reduce water intake and streamline for speed.
