Balanced Fit6.4mm clearance. Comfortable everyday wear with room to spare.

The Garmin Forerunner® 165 Music wears larger than the Garmin Vivoactive 6 (43mm vs 42.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin Vivoactive 6 is the slimmer of the two (10.9mm vs 11.6mm), so it slides under a cuff more easily.

On the wrist the Garmin Vivoactive 6 feels lighter (36g vs 39g, case only).
