Built for the water

  1. 01

    Feels like nothing

    At 18 grams, the band disappears after the first length. No straps across your palm, no drag.

  2. 02

    Reads every pull

    Nine sensors capture force, angle and tempo 400 times per stroke — the detail a coach sees from the deck.

  3. 03

    Tips, not spreadsheets

    After each swim you get one clear thing to work on next time. Not forty graphs.

  4. 04

    Seven days per charge

    A week of daily sessions on one charge, and a magnetic dock that dries as it charges.

−5.3s

Average 100 m time saved by members after six weeks of training with the band.
