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.
