Here is super warm Winter Jacket, made for us by the guys at Snugpak.
Made in the UK using the finest and latest materials. It has a Softie Premier filling and a Paratex Light outer. This is the ideal year round jacket, which is rated to -10 degrees. It packs down very small into its own stuff sack, and can easily be carried in your rucksack as a "just in case" jacket.
The winter jacket is soft to touch, and is very lightweight (approx 750g). It is water repellant and carries a British Standard Spray Rating of 4 Minimum as well as being wind proof to the industry standard of 3 cubic feet per minute.
The jacket is also highly breathable and has excellent wicking properties (will transmit 12 litres of moisture per m2 per 24 hours).
