First, let me say that generally OR makes terrific products. I am disappointed with these mittens, which I field-tested on the slopes of Banff, Alberta, Canada. I was thrilled that the mittens came with a mitten liner. Unfortunately, the liner is not warm. OR needs to put a warm polartec liner inside the mitten. My main problem with the mitten was they are did not keep my hands warm, even with hand warmers inside the mitten. OR needs to get away from these gloves and mittens that you can text with. The focus needs to be on warmth. Also, there was not enough fiber-fill with ruching and seaming , so the mittens themselves did not keep my hands warm. I would also prefer a shorter "sleeve" on the mitten. Yes, I did like the straps on the mittens -- a nice feature. To sum up, I think the mittens are maybe too breatheable. I would prefer my old-fashioned mittens that retained my hand/body heat. I would then dry out the mittens in the evening by a fireplace. Sorry, but these were not a good fit for me. I need to now shop for $30 or $40 fleece liners to salvage my purchase.
