Why buy each?

Garmin Fenix

64GB storage and faster maps

Double the map storage of the Fenix 8, with 50% more RAM and 30% faster map panning for routable built-in maps.

AMOLED or Solar: choose your battery priority

AMOLED on every Fenix 9, with up to 29 days on the 51mm. The Fenix 9 Pro Solar reaches up to 57 days with solar charging for trips where charging is impossible.

New training tools

Stamina zones, expanded rucking with adjustable pack weight, and indoor rowing metrics join Garmin's existing training analytics, plus a 40m dive rating.

Garmin vivosmart 5

Garmin Body Battery in a band

Body Battery energy monitoring — the feature Garmin is known for — in a wristband that's thinner than most fitness trackers.

HRV status and stress tracking

Continuous heart rate variability monitoring and all-day stress tracking give a more complete picture of recovery and readiness than step counts alone.

All data syncs to Garmin Connect, compatible with thousands of third-party apps, coaches, and integrations across the Garmin platform.
