Irish Fiendwrote a review of Black Diamond Mercury Mitt on January 25, 2007
If you ever have to spend the night in the backcountry during the winter, MITTS can be the difference between being functional and having fun or being one of those too-ultralight people who ONLY brought gloves and has to hide in their sleeping bag as soon as it gets colder. These Mercury Mitts are made for the winter temperatures you will encounter in the lower 48 states after dark or during storms. It is important to note that they are not too warm, meaning they can be worn on very cold days when you are moving also. Many Himilayan/Alaskan temperature rated mitts never get much use out of those altitudes and climates. This is a durable mitt with the appropriate warmth you need to actually get a lot of use out of it and not have it gather a lot of dust.
