running vest phone holder for heavy phone
Guide / 01
Measure and weigh your complete setup
Include the phone case and attachments when checking the 20 × 13cm chest pocket. A larger or heavier phone can sit differently from a small handset, even if its dimensions fit.
Guide / 02
Adjust the vest with the device loaded
The waist belt adjusts from 26–40in. Put the phone in the zipped chest pocket, set the vest over your running clothes and check breathing, arm movement and pressure while walking.
Guide / 03
Build up gradually
Try a short, easy run before carrying a heavy device over a long distance. No maximum phone weight or bounce-free performance is specified; use a different carrier if the fit feels unstable.
Good to know
Questions, answered.
Is there a maximum phone weight?
A maximum device weight is not specified. Test your phone in the vest and stop using it if the loaded fit feels uncomfortable.
