The Alti mitts are nicely insulated and well-constructed. The inner liner can be removed, and this is a good thing since the mitt tends to be on the bulky side. The leather is stiff and will need a bit of a workout to allow for a more comfortable grip. I live in Northern Ontario where winters are long, cold and crispy. I enjoy winter outdoor adventures such snowshoeing /skiing. I'm hoping that my frosty fingertips will be a thing of the past! I will test out my Alti mitts later this year since Canadians are now on "winter holiday"!
