comfortable running vest phone holder
Guide / 01
Set the vest up for your body
Wear it over your planned running top and adjust the waist belt until it feels secure without restricting breathing. Check that the shoulder straps lie flat and the chest pocket sits comfortably.
Guide / 02
Test the phone and pocket load
The chest pocket measures 20 × 13cm; each shoulder pocket measures 10 × 5cm. Try the contents you intend to carry and move naturally to notice pressure or shifting.
Guide / 03
Decide from a short trial
Comfort cannot be predicted from a product description alone. Walk, jog and reach for the zip before committing to a longer run, and consult Amazon UK for current sizing information.
Good to know
