running vest phone holder for teenagers
Guide / 01
Measure the wearer, not just the age
The waist range may not suit every teenager or body shape. Measure over the intended running layer and confirm the belt can be adjusted comfortably before buying.
Guide / 02
Check the phone and case
The chest pocket is 20 × 13cm. Measure the phone with its case and compare it with the pocket; the two shoulder pockets are smaller at 10 × 5cm each.
Guide / 03
Agree a practical safety routine
Before a run, make sure the phone is charged, the vest is adjusted and the wearer knows how to access the device when stopped. This product is not a substitute for route planning or supervision where needed.
Good to know
Questions, answered.
