no bounce phone holder for running
Guide / 01
Adjust the vest to your layers
The waist belt adjusts from 26–40in. Try the vest over your intended running top or jacket, then move your arms and breathe deeply to check comfort.
An adjustment that feels secure while standing may feel different once you start running. Recheck the fit with the pockets loaded.
Guide / 02
Check phone size and weight
The chest pocket measures 20 × 13cm. Include the case, camera bump and accessories when measuring, and consider whether your device is heavy for your preferred carry.
Two zipped shoulder pockets measure 10 × 5cm each. Keep small hard objects separate from the phone and avoid overfilling the vest.
Guide / 03
Test the set-up gradually
Close every zip and take a short, easy run before using the vest for longer distances. Adjust or remove items if the phone shifts or presses uncomfortably.
The pocket is water-resistant, not waterproof. Use a separate waterproof pouch in heavy rain.
