Under Armour ColdGear Reactor Running Gilett

Under Armour have solved the problem of being too cold when you start running or too hot when you get going. ColdGear Reactor actually adapts to what you're doing and keeps you warm whilst on the go.

Constructed using a lightweight reactor technology, the Under Armour ColdGear Reactor Running Gilet adapts to your activity level for optimum breathability and warmth. Dual-layer ColdGear fabric features an ultra-warm brushed interior and a smooth, fast-drying exterior to keep you cosy but dry when the temperature drops. Enriched with moisture-management technology, this top wicks sweat away from the skin for quick evaporation, so you stay damp-free and comfortable during intense exercise. UA Storm technology repels water without sacrificing breathability, helping to protect you from the elements. A four-way stretch construction provides a full, unrestricted range of motion ensuring you can get the most out of your workout. Woven overlays on the chest provide added durability and protection and allow for a tighter fit that hugs the body and moves as you do. The adjustable knit collar can be worn up for full-face coverage on your coldest runs, whilst the invisible side zip construction allows for easy on and off. The gilet features a secure, zip back pocket to hold your cards or keys, for secure storage on the go.
