[No Guesswork, Made For Fitbit Air] Compatible with Google Fitbit Air only. Simply press the tracker into place for quick, tool-free installation. Not compatible with other Fitbit models. Fitbit Air tracker is not included. [Free Your Wrist, Keep Your Routine] Wear your Fitbit Air on your upper arm or ankle when wrist wraps, lifting straps or workout gloves get in the way. Focus on your workout, or keep wearing the watch you love, without adding another device to your wrist. [Your Fit, Your Way] Our Fitbit Air bicep band features a sliding buckle that adjusts continuously from 9.8 to 15.7 inches (250400 mm), letting you fine-tune the fit without being limited to preset holes.

Adjust it until it feels comfortably snug to help reduce shifting. Measure your upper arm or ankle before ordering. [Comfort That Moves With You] Lightweight, breathable stretch nylon flexes naturally with your upper arm or ankle, providing a soft, comfortable fit from workouts to daily activities. [Keep Your Tracker Where It Belongs] The fitted holder secures your Fitbit Air around the edges while leaving the sensor area open against your skin, so your tracker stays supported without blocking skin contact as you move
