Bison leather offers the best ratio of softness to strength allowing the athlete to feel the implement and durability to withstand the rigors of throws training. 2.5mm leather will be more soft and require less "break in" time. 4mm leather will take the most time to "break in" and is only suggested for throwing heavy implements or athletes requiring significant finger support.
