The Mulholland Shorthorn #CSE4030 is made from a treated canvas known as "endurance" and accented with leather trim. The use of endurance with leather trim give this model a completely different look than its all leather counterpart(Mulholland #AL4030). The rigid top allows the bag to hold itself open during packing and unpacking and the solid metal snap-open buckle on the front pocket makes the Shorthorn #CSE4030 as functional as it is beautiful.
