"While wearing the AMP, I literally felt like I am bred for the water. My walls are sharper, my energy boosted, and my stroke technique improved. I feel so natural and smooth in the water. Now only if I had gills!"

Understanding Drag

Drag is commonly misinterpreted in swimming. Many people believe that the highest amount of drag in a race occurs as the water passes over the skin. While this effect does cause some resistance, two other factors exist that produce exponentially greater drag effects in the water:

• Volume Drag – The resistance of the swimmer’s body shape against the water
  
  Simple physics states that a swimmer with a larger body shape will displace more water. Because of this, the more water that pushes against a larger body shape, the further this water will need to travel in order to get around the moving swimmer.
  
  The AMPhibian suit uses smart compression panels and stitching to tighten the body shape into its most compact yet natural form. The result is a smaller ‘opening’ in the water and less displacement while swimming.
  
  
  
• Turbulence Drag – The wave and turbulence resistance around the swimmer as one moves through the water
  
  Water does not stay still, and it is this constant movement of water that creates the largest resistance effect upon moving bodies. Swimmers make waves while they swim and these waves bounce at varying angles and differing speeds, creating a chaotic effect of motion around the swimmer’s body. This turbulence works directly against the swimmer’s path through the water, dramatically decreasing their speed.
  
  The AMPhibian suit uses an exaggerated low-profile design to help streamline the swimmer’s body shape in the water. By reducing the various fluctuations and forms on the body, the overall turbulence that is created by the swimmer can be decreased. Essentially, the AMPhibian aims to open up a small hole in the water and close it behind the swimmer to reduce any agitation in the water. Thereby the AMPhibian creates a smaller turbulence wave around the swimmer, dramatically decreasing the adverse drag effects.
  

Creating Technical Cues Working with the top coaches and swimmers in the world, the FINIS development team integrated unique breathing and body-positioning technique aspects into the AMPhibian. The result promotes the swimmer to maintain an optimal "Aquatic Signature" during their race. Stabilizing Strips reinforce correct posture in the water. Indicator points are engineered into the suit and heighten senses around the chest and back to cue easier breathing techniques. Smart compression panels help tighten the overall body shape in specific areas to create the most efficient body position alignment Low profile zippers squeeze and streamline the entire body Durability & Functionality After watching many suits rip right off swimmers’ bodies during championship meets, the FINIS Product Development Team designed the AMPhibian to last. Over 75 different types of fabrics were tested, and multiple types of bonding and stitching applications evaluated. The resulting "Frog Skin" fabric is sleek, slippery, and tough. Lightweight porous polyurethane panels provide strength without adding weight in the water Tough flat-lock bonded stitching creates a smooth and strong seam line Zippers down the back and ankles allow the suit to be easily put on and off, greatly reducing stress points and general wear-and-tear Smooth lining creates a comfortable fit that does not rub or pull Smart panel positioning reduces excessive force at stitch lines

AMPhibian – Bred for the Water

Using their core technical knowledge, the FINIS Product Development Team has truly created a natural speed suit for swimming. The AMPhibian takes a walking land animal and transforms them into an aquatic predator. Unique and proprietary engineering aspects allow the swimmer to enhance their 'feel' for the water, reduce exponential drag effects, and support an improved "Aquatic Signature" for sustained energy systems.

Ultimately, the AMPhibian allows the swimmer to be more efficient in the water.

Tested and Proven

Creating the AMPhibian was a very scientific process which required countless hours on pool decks and in laboratories. The following is a quick sampling of the testing conducted by the FINIS Development Team in partnership with various world class athletes, coaches, medical doctors, and engineers:

• Water Flume Testing
  
  Powerful water jets are positioned in front of a swimmer or solid body to understand the fluid dynamic properties of a particular shape, form, or fabric. A 3D model can also be extrapolated using sensors to analyze specific drag properties, while also determining the ideal "Aquatic Signature" for a swimmer.
  
  
  
• Fabric and Stitch Testing
  
  Stretch and performance testing was conducted on over 75 types of fabric material and 10 different stitching mechanisms. Tensile forces were measured to determine the best combination of fabrics that would create ideal compression traits and maintain durability. Suits were then UV and chlorine tested to determine longevity over 80 swims.
  
  
  
• Body Scanning
  
  3D models were created by analyzing the body shapes of athletes around the world. The result provided detailed insight for specific fabric panel placement and the integration of the smart compression network. Scans were also made with athletes in the suit to better understand specific stress points and allow for a full range of motion and flexibility.
