Eugenewrote a review of Marmot Expedition Mitten - Men's on January 8, 2017
Familiarity: I've used it several times
Fit: Runs large
I initially tried the Black Diamond Mercury Mits, and found the divided index finger uncomfortable. I returned them, and purchased these instead. They run large, so I exchanged a medium for a small (my hand measures 7in from the tip of my middle finger to where my wrist begins). These gloves are soft, comfortable, and so warm!
My hands run cold, and these gloves keep my fingers warm into the single digits. I have not taken them into the negative F range, but I had toasty hands/fingers with activity at around 8F.
