I'm with Fatum on this one. The best gloves for everyday use (in
my experience) are the Thinsulate-lined work gloves, available from
almost any hardware or home improvement store. These gloves are
reasonably thin to offer maximum manual dexterity with the digits,
yet keep your hands and fingers warm even in sub-zero (Farenheit!)
weather. The palm area is usually lined with some kind of
faux leather material to
aid in gripping objects. Plus, for whatever reason, they're usually
priced really cheap--I see them at the local Home Depot all the
time for under US$5.
The ones I use have lasted several winters already.
