Pair of simple leather gloves
These normal gloves have been coated with adhesive extracted from the filament of a cave fisher. They are extra-ordinarily sticky and vastly assist in climbing. Wearers gain a +25% to any climbing checks. The gloves must be stored carefully wrapped in wax paper until desired for use. Once exposed to air (and dirt from whatever surface is being climbed), they remain beneficially sticky for one hour. Afterwards, they become a regular pair of dirty gloves.
