running vest phone holder
Guide / 01
A vest-style phone carrier
The product combines a front phone pocket with two shoulder pockets in a lightweight running vest format. It is designed to carry a phone and a small selection of essentials, rather than replace a full running pack.
The chest pocket measures 20 × 13cm. The two shoulder pockets each measure 10 × 5cm, giving you separate places to store small items.
Guide / 02
Adjustable sizing
The vest is listed as unisex and one size, with a waist belt that adjusts from 26 to 40 inches. Check the range against your body measurements and the layers you expect to wear, especially if you run in a thicker top during colder months.
Before a longer run, adjust the straps, zip the pockets and move around to make sure the vest feels comfortable for your own build.
Guide / 03
Water resistance and care
The chest pocket is water-resistant, but the product is not described here as a fully waterproof phone case. Keep electronics protected in downpours and never submerge the vest.
After use, follow the care instructions on the product-care page. Let the vest dry fully before storing it and avoid harsh cleaning methods that could damage the fabric or fastenings.
