Dan Mcwrote a review of Outdoor Research Alti Mitten - Men's on December 11, 2017
Familiarity: I've used it once or twice and have initial impressions
This is a follow up review of the Hestra Army Glove that is a great glove but isn't that warm.(https://www.backcountry.com/hestra-army-leather-gore-tex-xcr-glove?s=a) I purchased these mittens specifically for skiing on cold days (below 20 degrees F). I had a chance to use them this week in single digit weather. They are very warm and I'm happy with my purchase. First first day in them was a pretty cold day. The type of day that hands out of gloves got extremely cold after 30 seconds. When I put the gloves back on I balled my hands up in the large part of the mitten and they were toasty within 30 seconds. I put my thumb back in place and I was good to go. I was worried that the glove would be too bulky to get a ski pole strap over them. That wasn't a problem. First impression was this is a well made glove, waterproof, and very warm.
