Really good jacket. Also, even if it's shell, it doesn't rustle

A well thought out jacket. The only thing is that there is no separate pocket for the lift ticket.

Really good shell jacket, I was on a week-long fell hike and we got water up to our necks at times, even quite badly. It was the first trip I did with just one jacket.

A well-designed and functional product. The only downside is the zipper, which is very stiff and difficult to get moving. It has been like this from the very beginning; hopefully, it holds up.
