Fingerless gloves, the gardener's best friend in winter:
Also a hiker's best friend. I wore a similar pair last week (see "Hike of the Week: 7 Miles to Stinson Beach, CA") and am happy to report I had full finger dexterity when unwrapping my tuna sandwich and various trail snacks.
Above: A pair of brown Fingerless Gloves made of a wool and nylon blend have elasticized wristbands to keep out the cold; available in three sizes, the gloves are $12 from Brook Farm General Store.
