Garmin Descent™ G2 vs Garmin Vivoactive 6Size, Specs & Wrist Fit Compared

The Garmin Descent™ G2 wears larger than the Garmin Vivoactive 6 (45.5mm 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 15.2mm), so it slides under a cuff more easily.

On the wrist the Garmin Vivoactive 6 feels lighter (36g vs 65g, case only).
