The Rival open-back kneeskin in black blue is FINIS' elite level racing suit designed using three main principles:

1. Compression - Increased compression has been added to key area's such as the upper thighs, supporting muscles as well as streamlining the body to reduce drag. 

2. Robust seam structure - Seams have been carefully positioned to not only strengthen the fabric but a key seam running from front to back, locks the swimmer into the optimal body position, increasing efficiency and speed.

3. Fit - The elite fit of the Rival swimsuit ensure the balance between compression, support and flexibility is well maintained.

The Rival kneeskin has been packed full of performance-enhancing features, all designed to ensure you perform your best on race day. The Rival has also been coated with a hydrophobic coating ensuring you glide through the water with ease and are not held back like tradition fabrics would. 

The FINIS Rival is FINA approved for competition use
