Tree workers go through gloves like they're trying to break a record, so Notch has made ArborLast Gloves to try to end that practice. The base palm is made out of flexible leather with reinforced patches strategically placed in high-wear spots. All of the leather is pre-curved prior to sewing, which makes the gloves feel already broken in the first time you put them on. The backs of the gloves use an air-mesh for breathability to keep your hands cool, making the ArborLast super durable and really comfortable.
