running vest with phone and gel pockets
Guide / 01
Separate your phone from running fuel
The chest pocket is zipped and measures 20 × 13cm. Two shoulder pockets measure 10 × 5cm each and may suit compact items, but gel sachet sizes vary and are not specifically guaranteed to fit.
Guide / 02
Test a loaded setup before a long route
Measure your phone with its case and compare gels with the shoulder-pocket dimensions. Put the phone in the chest pocket, close each zip and walk or jog briefly to check that the contents feel manageable.
Guide / 03
Plan fuel for the distance
This is a phone and small-item carrier, not a high-volume race pack. If you need multiple gels or other nutrition, confirm capacity from the listing or choose a pack designed for your planned fuelling strategy.
Good to know
Questions, answered.
Will the shoulder pockets fit energy gels?
Each shoulder pocket measures 10 × 5cm. Compare your gel sachets with that size; fit is not guaranteed for every brand.
