running vest phone holder with large pocket
Guide / 01
Measure the full phone set-up
Measure the phone with its case, camera bump and any grip or wallet attachment. Compare the result with the 20 × 13cm zipped chest pocket and allow space to close the zip.
Guide / 02
Separate the phone from small essentials
Two zipped shoulder pockets measure 10 × 5cm each. They can keep smaller items apart from the phone, but are not substitutes for a second large compartment.
Guide / 03
Check the listing if you need more capacity
No larger chest-pocket size is claimed beyond the stated measurement. If you need room for a bulky device or several items together, confirm the photos or choose a higher-capacity carrier.
