If your looking for a comfortable and style mitt on the hill then these things are great bit I found they fell short when it came to more serious use.
I took an hour hike and they ended up getting soaked. They weren't super breathable or waterproof so I found my hand getting sweaty from the inside and wet from the outside.
On the plus side they were pretty warm so even when wet they held up at -10.
Bottom line - great casual mitt but for urban or backcountry I'd rock something more waterproof and keep these dry for the trip down.
