I bought these gloves to wear while riding my motorcycle. I like to ride year 'round, and keeping my hands warm was a problem. While I won't say my hands stay toasty warm now, they definitely stay comfortable even on lengthy rides whereas before they were like chunks of ice. I would think they would work well for any cold weather activity.
