running vest phone holder for triathlon

Guide / 01

Confirm the race regulations

Event rules can restrict what may be worn or carried during each discipline. Check with the organiser before using a phone vest in a sanctioned race.

Guide / 02

Consider when you need the phone

The zipped chest pocket measures 20 × 13cm. If you plan to carry a phone during training, check fit and access outside the race context first.

Guide / 03

Do not assume swim or weather protection

The pocket is water-resistant, not waterproof, and the product is not described for swimming. Use equipment intended for each discipline and protect electronics separately.
