All of the clothes are made of a very lightweight material and the LEDs weigh only 4.7g each so don't add any significant weight or added bulk. The jacket features a strip of blue fibre optic cable embedded in to the upper arms that can be set to constant light or flashing at the touch of a button. The trainers feature a removable LED light that sites on the tongue of the shoe under the laces. The lights come with a USB connector so that they can be charged easily.
A statement on the Pro Direct website said: "The PUMA Nightcat range features technologically advanced running wear enhanced with Visicell highly reflective materials designed to keep you 360 degrees visible. The Faas 600 V2 Nightcat Powered running shoes feature innovative, rechargeable LEDs with optical fibres on the tongues that illuminate for enhanced visibility."
