Do Instinct 2 bands fit the Instinct 3?
Instinct 2 Solar bands fit the Instinct 3 45mm, since Garmin lists QuickFit 22 for both. They don’t fit the 50mm, which needs QuickFit 26. The Instinct 2S Solar and Instinct E 40mm take QuickFit 20, which fits neither.
Which other Garmin bands fit the Instinct 3?
QuickFit 22 also fits the Instinct E 45mm, Instinct Crossover, Forerunner 970 and Fenix 8 47mm. QuickFit 26 also fits the Enduro 3, Fenix 8 51mm and Fenix 9 51mm.
