what to look for in a running vest phone holder
Guide / 01
Start with phone fit and pocket closure
Check the compartment dimensions, opening and fastening. The Défi chest pocket is zipped and measures 20 × 13cm; compare your phone with its case and allow room to close the zip.
Guide / 02
Check the body fit and smaller storage
Review the 26–40in waist adjustment and the two 10 × 5cm shoulder pockets. Think about your running layers, keys and compact essentials, then test the loaded vest in motion.
Guide / 03
Verify claims that matter to your route
Do not assume waterproofing, reflective panels, hydration storage or special fabric performance unless the listing confirms them. Use Amazon UK for current product and order details.
