Product description

The Rival open-back racing leg swimsuit from Finisu will bring you one step closer to your dream victory. They're packed with cutting-edge technology to support your performance and boost your speed as you swim.

Rival's elite racing swimwear is designed to meet three essential requirements: compression, durable construction and comfort.

The construction of this swimsuit utilizes two fabrics: a stretch fabric in one direction to increase compression, while another stretch fabric in the other direction ensures optimal range of motion. This combination of two fabrics supports the work of the muscles and increases their efficiency. The seams of the swimsuit are strategically placed to hold the two fabrics tightly together and increase the compression properties of the swimsuit in their respective areas.

The swimsuit also features a three-panel abdominal system that provides the swimmer with the compression and mid-body firming she needs.

All of this also means that the swimsuit reduces water resistance, which increases the hydrodynamics of the swimmer's body. The hydrophobic finish then ensures that the swimsuit is less absorbent, so that the swimsuit does not absorb too much water and therefore remains very light in the water.


Swimwear provides an advanced level of compression that ensures maximum support fo body and its stability.

This type of swimsuit is with pants. The benefit of these panties is that it fits perfectly and adapts to your body.

These swimsuits have an open back that ensures maximum freedom of movement.

Approved and certified by the International Swimming Federation World Aquatics. It meets all international standards and allows start at prestigious races.

Finis

Finis built its success off a monofin. The origin of the brand has been considered to be since 1993, but the founders had been involved in the development of the fins a few years earlier. Other technical products such as the central snorkel and Tech Toc began to be added alongside the monofins. The Finis brand still has many swimming gadgets used by many coaches to master swimming technique. As one of the few brands, it also produces quality swimming electronics. Its hallmarks are black and yellow products and logos.
