running vest with secure phone pocket
Guide / 01
Check the pocket closure and space
The front chest compartment closes with a zip and measures 20 × 13cm. Measure your phone with its case fitted, leave room for the zip to close, and avoid forcing a device into a tight pocket.
Guide / 02
Secure the contents before moving
Close the zip fully and adjust the vest over your running layer. Try a walk followed by a short jog with your phone inside; this helps you notice movement or pressure before a longer outing.
Guide / 03
Understand what “secure” can mean
The dimensions and zip are confirmed, but no impact-protection or anti-theft rating is specified. Keep the phone protected from hard objects and use a separate protective case where your route or conditions call for it.
Good to know
Questions, answered.
Is the phone pocket guaranteed not to bounce?
No fit or bounce-free result is guaranteed. Adjust the vest, use a phone that fits and test it on a short run.
