Perfect for running
I'm 50 and have hated wearing gloves since -- well I was probable pitching them out of my stroller. I need some insulation for running in sub 20 degree mornings but my regular gloves are too heavy and soon soak with sweat. These are light, breathable and provide just enough insulation on cold mornings. I use these without an outer glove, and with their very light weight I could see the possibility of durability issues if used them differently but for keeping hand warm while running they're great.
