Running vest for large phone
A large phone can be harder to fit into running gear, particularly when a thick case is attached. The Défi vest has a 20 × 13cm chest pocket; check your complete phone set-up against it before ordering.

running vest for large phone
Guide / 01
Measure height, width and thickness
Measure the phone with its case fitted, including raised camera lenses, grips or a wallet attachment. The pocket’s stated dimensions are 20cm high by 13cm wide, but the device shape and opening also affect how easily it fits.
If the phone is very close to those dimensions, do not assume it will slide in comfortably. Check the current listing photos and product details first.
Guide / 02
Keep the chest pocket for the phone
Two zipped shoulder pockets measure 10 × 5cm each and can keep a key or gel separate from the device. Avoid overloading the smaller compartments or putting hard objects beside the screen.
The chest pocket is water-resistant, not waterproof. A large phone still needs separate protection from heavy rain or water exposure.
Guide / 03
Fit the vest before a longer run
The one-size unisex design adjusts from 26 to 40 inches at the waist. Try it with the phone and running layers you plan to use, then walk and jog briefly to check how the load feels.

Is the pocket large enough for every large phone?
No. The chest pocket is 20 × 13cm, but phone dimensions and cases vary. Measure the full device and check the fit before buying.
Can I use a bulky wallet case?
