At the end of 2014 I hiked Mount Moriah and my fingers nearly froze off on the summit. I knew I needed to purchase suitable hand protection in order to hike through the winter.
I decided I wanted mittens and glove liners. Mittens were the logical choice as they keep fingers warmer than gloves, but I also wanted the option of taking them off for short periods of time to get into my pack, unfold a map, take photos, etc. Glove liners would give me the dexterity of my fingers without leaving my hands exposed to the elements.
