Keeping hands warm while sleeping is not a problem with me since i sleep in a warmer bag if its really cold. To me hiking with cold hands is miserable. I have a pair of Marmot lobster gloves that I bought used for 50 bucks used on Ebay. They are super warm in any temp. I overcompensate for warmth as an adult since when I was a child playing in the snow I was always cold - cheap coat and shoes. Now i'm Mr. Toasty in layers.
