A soft furry pelt harvested from a wolf-like creature. It is difficult to pierce and insulates well against cold.
The following animals provide wolfskin.
Wolfskin is the 8th most protective textile in the game, and has good cold insulation and average heat insulation. This make it is a very good candidate for dusters and other protective clothing in the early game, especially in cold biomes. However where the environment permits, it should be replaced in the mid-game by more protective materials such as devilstrand, with dusters receiving priority. As it provides enough sharp protection for even pants and button-down shirts to have a chance to stop attacks, though mostly only at higher qualities, it can be valuable to transition to using wolfksin for those items to save limited stocks of better materials for dusters where they will have more impact while still providing some chance to deflect a blow after AP. Additionally their good cold insulation may permit more protective but less insulative materials to be used for the duster, or allow the wearing of a duster where only a parka would be sufficient otherwise.
For use in furniture, it has a middle-of-the-road beauty factor, but its eventual redundancy as clothing and the demand for more beautiful textiles like Thrumbofur in other roles makes it a decent choice for improving furniture beauty once the colony has transitioned to more protective textiles.
Wolfskin is a new leather type added in update 0.19/1.0 as a merger of different fur types from wolves. It includes timber wolfskin, arctic wolfskin, and (because its in the same general category) warg fur.
