Compare your measurements with the adjustment

Check the chest pocket for your phone
The zipped pocket measures 20 × 13cm. Include your phone case and attachments in the measurement and leave room for the zip to close.
Guide / 03
Confirm current variants on the retailer page
A distinct L/XL version is not confirmed here. Check the Amazon UK listing’s selectable options before checkout.
