running vest phone holder for foldable phone
Guide / 01
Measure it folded and in its case
Include the hinge, case thickness and any camera bump. Compare the complete folded device with the 20 × 13cm pocket and leave room to insert it and close the zip.
Guide / 02
Check the fit while moving
A foldable phone may be heavier or thicker than a standard handset. Place it in the chest pocket and check comfort while walking before taking it on a run.
Guide / 03
Avoid forcing a close fit
If the device catches on the opening or presses uncomfortably against you, use a different carrier. The listed dimensions are a guide, not a model-specific compatibility promise.
Good to know
Questions, answered.
Will every foldable phone fit?
