Guide / 01
Measure over your running layers
The waist belt adjusts from 26 to 40 inches. Take your measurement over the clothes you expect to wear, then check shoulder and chest comfort when the vest is loaded.
A one-size label does not guarantee the same fit for every torso or shoulder width. Use the product photos and measurements, and try a short test run before relying on the vest for a long session.
Guide / 02
Check the phone pocket and smaller storage
The zipped chest pocket measures 20 × 13cm. Two shoulder pockets, each 10 × 5cm, provide separate storage for a key, card or gel.
Measure your phone with its case, then compare it with the chest pocket. Avoid overfilling the smaller pockets or placing hard items next to the phone.
Guide / 03
Use it for phone and essentials
The vest is designed for a phone and a few small items, not as a large-capacity training pack. Plan water and other equipment separately for longer routes.
The chest pocket is water-resistant, not waterproof. Keep electronics protected in heavy rain and follow the care instructions after use.
