Peter S.wrote a review of Outdoor Research Meteor Mitten on February 27, 2013
Shortly after I bought these, I spent a day on Rainier doing crevasse rescue training and these mittens got SOAKED. However, I was constantly taking the mitts off and on to manage rope, set anchors, mess with prussiks, etc, etc, and it was pissing rain all day long.
I think these mittens would work very well during a climb where there is mostly sustained trekking with very little contact with snow/ice, constant removal etc.
I found the fleece liner mittens to be a bit excessive as well; I agree with the previous posters comment that thin glove liners function better.
