Guide / 01
What fits in the chest pocket?
The chest pocket measures 20 × 13cm and is intended for a mobile phone. Check your device with its protective case attached; phones vary in size, and a bulky case can change the fit.
The pocket closes with a zip. Do not force a device that is too large through the opening, and avoid placing hard objects in the same compartment as the screen.
Guide / 02
Three zipped pockets in total
Alongside the main phone pocket, the vest has two shoulder pockets measuring 10 × 5cm each. They provide separate space for small items such as a key, card or energy gel.
- One 20 × 13cm zipped chest pocket
- Two 10 × 5cm zipped shoulder pockets
- Unisex, one-size fit with a 26–40in adjustable waist belt

Fit it over your normal running layers
The adjustable belt lets you set the fit across its stated range. Put the vest on over the shirt or light layer you plan to wear, adjust it until it feels secure without restricting movement, then check the pockets while walking and jogging.
The chest pocket is water-resistant. That is not the same as waterproof, so use extra protection for your phone in heavy rain or when conditions are uncertain.

A quick buying checklist
Measure your phone with its case, check the 26–40in waist range, and decide what you want to carry in the shoulder pockets. The Amazon UK listing provides the latest price, stock and delivery details.
