Polar Grit X Bundle

The Polar Grit X multisports watch delivers military-level durability in a sleek, lightweight package. This bundle includes a Polar H10 heart rate sensor, saddle bag and bike mount. There are no compromises with this watch; it is packed with training features and tools and has the battery life for the longest adventures. Used together with the Polar Flow app, you can keep track of all your activities and even sleep data, and sync to your other favourite apps such as Strava or TrainingPeaks.

Plan routes and import to the Grit X so you can concentrate on enjoying your session, with real-time, turn-by-turn guidance. You can also check the current weather as well as get a two-day forecast on the watch, allowing you to plan accordingly.

Silicone wristbands make for comfortable wear, and they can be switched out to personalise your look. The bike mount allows for easier viewing of data or maps when on two wheels.
