how tight should a running vest be
Guide / 01
Adjust over the clothes you will wear
The waist range is 26–40in. Set the belt over your usual running top or jacket, then check that you can take a full breath and move your arms and shoulders naturally.
Guide / 02
Check the fit with the phone inside
Put a phone that fits the 20 × 13cm chest pocket inside and close the zip. Walk, bend gently and jog briefly to notice pressure, shifting or uncomfortable movement.
Guide / 03
Do not tighten to solve every movement issue
If the vest feels restrictive or continues to move, readjust it or consider another carry style. No universal fit setting or bounce-free guarantee is specified.
