I teach skiing and I have to take gloves on and off constantly throughout class. I am outdoors on snow, all day long, all season long (I know great life right?) I never know what my students will need, what the weather requires etc. These mitts are very versatile to be worn, not worn (wrist straps are so helpful) with liners or without liners. I also use power tools when setting up for classes and these allow me to handle that job as well. Very thick, durable, and very warm. Superior to any other mitt I've used.
