"Used this jacket for a week of winter mountaineering in Scotland, including the wrath of a storm. The jacket was outstanding! Excellent breathability and totally wind proof even in 70mph gusts. Love it!"

"I own two of these jackets and they have never let me down. Dry as a bone and great for layering with other gear. All the mod cons in one outdoor jacket. Finally, real good value for money."

"I've had the women's version of this jacket for 3.5 years now in Scotland. It's done over 50 munros in all weathers and all types of snow and it's never leaked, I am always dry and warm. "
