As far as wool versus synthetic, I usually go to synthetic for base layers and the like, but lately I was searching for a good mid-weight glove for use while hiking in the winter, enter the Black Diamond WoolWeight glove.
First, I did size up for these gloves, the other Black Diamond gloves I have are size large (except my over mitts), but after trying on a pair I went for the extra large, it was the right choice, it helped with the dexterity I was after. But truly where these gloves shine is how quick they dry and the comfort they provide during hiking efforts.
I wore these on a snow shoe day hike on Mt. Watermann in the Angeles National Forest with Saveria and our WTC class. At the first rest stop I was adjusting my snow shoes and I was easily able to deal with the straps but my gloves did get covered in snow, they felt damp on the outside but my hands were still warm. We began to hike, and the next time I checked my gloves were dry.
The next I wore these as my main gloves was on a three day snow camp in the Sierras. Again the range of these gloves was perfect, from hiking during the day to cold 20 degree nights.
I love gloves and finding the perfect ones for a specific situation is always a fun challenge. These a great all arounders that pack small and cover a big range.
