running vest that fits phone with case
Guide / 01
Measure beyond the handset body
Include the case, raised camera area, screen protector edges and any grip or wallet attachment. Compare the widest and longest measurements with the 20 × 13cm pocket.
Guide / 02
Allow room to insert and remove the phone
A device that only fits when pushed hard may be difficult to use on a run. Check that the zip closes without strain and that the phone can be removed without catching on the opening.
Guide / 03
Check your exact model before checkout
Phone dimensions differ across models and case styles. The product page does not guarantee case compatibility for every device, so use the Amazon UK listing and your own measurements to decide.
Good to know
Questions, answered.
Should I measure the phone with its case?
