## Long description

Griffin GB40139 is a black accessory designed to hold and protect a range of activity trackers, compatible with Fitbit Flex, Fitbit One, Fitbit Zip, Misfit Shine and Sony SmartBand. Supplied as a single piece, the accessory provides a soft, breathable mounting solution for everyday wear, workouts and sleep tracking. The band features a perforated brushed spandex construction with an inline pocket and a Velcro closure, and an included extension lets you convert the wristband to an armband for a more flexible fit.
Advantages
The soft, breathable material provides comfort for continuous 24/7 wear, including sleep monitoring. The inline pocket secures supported trackers while keeping them accessible, and the Velcro closure enables quick size adjustments. The included extension adds conversion versatility so the same accessory can be used either on the wrist or as an armband. The black colour offers a neutral, unobtrusive look that pairs with everyday clothing and workout gear.
Suitable for
Wearing a compatible tracker during sleep for overnight monitoring
Everyday step and activity tracking when a comfortable band is preferred
Workouts where a wrist or arm placement is needed for convenience
Situations requiring temporary conversion from wrist to armband fit
Key specifications
Compatible tracker models: Fitbit Flex, Fitbit One, Fitbit Zip, Misfit Shine, Sony SmartBand
Colour: Black
Band material: perforated brushed spandex / nylon blend
Closure type: Velcro adjustable closure
Wrist fit: fits wrists up to approximately 21 cm (8.27 in) circumference
Armband fit with extension: fits arms up to approximately 40.6 cm (16 in) circumference
Tracker pocket internal dimensions: fits trackers up to 28 mm wide × 48 mm tall × 10 mm thick
How to use
Place your compatible tracker into the inline pocket with the device oriented so sensors and display (if applicable) align as intended. Fasten the band around your wrist using the Velcro closure and adjust to a comfortable, secure fit. To use as an armband, attach the included extension and refasten the Velcro so the band sits comfortably on the upper arm. Ensure the tracker sits flat against the band to reduce movement during activity and to maintain accurate readings.
Usage recommendations
For reliable sensor contact and comfort, wear the band snugly but not tightly; check the tracker position before exercise and after changes in clothing. Remove and dry the band if it becomes wet, and inspect Velcro and seams periodically for wear to maintain secure attachment.
