You can be sure to stay warm and active when the temperature drops, thanks to the lightweight Regatta Iceway Men’s Down Gilet.
It is filled with Premium duck down, which has been coated to help repel moisture and prevent clumping. A Durable Water Repellent coating has also been applied to the face fabric, which will help to shed any showers you are caught out in.
The 600 fill power ensures your core stays warm, whilst the stretch bindings and hem allows for a secure fit and maintains full freedom of movement to your arms.
The simple yet stylish design will be a superb addition to any wardrobe, being useful all year round – especially with our great, and often unpredictable, British weather.
