The Bioflow Sport Flex is a fully adjustable version of our original Sport wristband.

Designed to complement an active lifestyle, Bioflow Sport is a winning combination of powerful magnet technology teamed with a durable, waterproof silicone wristband. Each wristband contains a powerful Central Reverse Polarity magnet encased in a smooth and comfortable one-piece strap with a convenient buckle fastening.

The Sport Flex fits wrists measuring 16.5cm – 22cm.

PLEASE NOTE: Bioflow products should not be worn by anyone fitted with a heart pacemaker or other implant that could be affected by a strong magnetic field. Bioflow Sport wristbands are made of silicone. Silicone allergy is rare but those who experience it may have symptoms such as rashes and inflammation.
