Colbwrote a review of Burton Gore-Tex Mitten + Liner - Men's on December 9, 2013
Familiarity: I've used it once or twice and have initial impressions
These are great mittens. Just used them on a -5 degree day and they worked great. I love the new synthetic material on the palm. It is great that it allows touchscreen grab with the gloves on. All around a warm and durable feeling mitten. I generally shy away from leather palms to a synthetic palm, because synthetic is more durable and fully waterproof. I ordered other mittens in this price range and the Burton's were made from higher quality materials than the others.
2 things could be improved:
The Gore Leather mitten has a small course patch on the inside of the index finger for a goggle wipe. I wish Burton would have added the patch to this synthetic palm model as well. Also the wrist gaiters could stand to be about 1/2" to 1" inch longer. My old Gore mittens from about 8 years ago wore out, but they had a slighter longer gaiter which made use a little easier.
