Garmin Forerunner® 25 vs Garmin Lily® 2Size, Specs & Wrist Fit Compared
The Garmin Forerunner® 25 and Garmin Lily® 2 share a near-identical 35mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Lily® 2 is the slimmer of the two (10.1mm vs 13.9mm), so it slides under a cuff more easily.
On the wrist the Garmin Lily® 2 feels lighter (24.4g vs 31g, case only).
