unisex running vest phone holder
Guide / 01
What the unisex label tells you
The product is listed as unisex and one size, with an adjustable waist belt from 26–40in. The label does not establish a fit for every body shape or clothing layer.
Guide / 02
Compare your phone and preferred layers
The chest pocket measures 20 × 13cm and the two shoulder pockets measure 10 × 5cm each. Measure your phone with its case and test the vest over the clothes you run in.
Guide / 03
Choose comfort over the label
Adjust the straps and belt so the vest feels secure without restricting movement. If it does not sit comfortably on your body, the unisex description is not a reason to keep using it.
