sweatproof running vest phone holder
Guide / 01
Water-resistant is not sweatproof
The chest pocket is described as water-resistant. That is not a guarantee against sweat, heavy rain, immersion or moisture entering through the zip.
If your phone needs a sweatproof barrier, use a separate protective pouch rated for your conditions and check that it fits inside the 20 × 13cm compartment.
Guide / 02
Carry the phone securely
Measure the phone with its case and pouch attached, if you use one. Do not force the zip if the combined size is too close to the pocket dimensions.
Two shoulder pockets measure 10 × 5cm each, while the waist belt adjusts from 26–40in. Keep the load compact and test the fit before a longer run.
Guide / 03
Follow the product care guidance
After a sweaty session, remove electronics before caring for the vest. The stated care guidance is to hand wash gently and air dry; avoid bleach, ironing and tumble drying.
