Garmin
D2™ Air (010-02173-41)
Garmin
Vivoactive 3
The Garmin D2™ Air and Garmin Vivoactive 3 share a near-identical 43.2mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Vivoactive 3 is the slimmer of the two (11.7mm vs 12.4mm), so it slides under a cuff more easily.
On the wrist the Garmin Vivoactive 3 feels lighter (43g vs 46.3g, case only).
