You can wear your Fitbit Ultra comfortably in your pocket or on a bra. The Ultra can be clipped directly onto your waistband, or can be attached to thicker waistbands using the belt clip. Slip it into your wristband at night to track your sleep patterns.
The Fitbit Ultra tracker should hold up through normal use throughout the day. However, it is not waterproof and should not be worn in water or during activities where it might get wet.
We do not recommend wearing the Ultra tracker directly against your skin during vigorous workouts. Users who wear the Fitbit on their bra, waistband or any place that comes directly in contact with their skin during strenuous workouts see more display defects than those who put their Fitbits in their pocket during workouts.
Wearing the Fitbit Ultra tracker on a bra or waistband around your home or in the office should not be a problem.
