Calfskin Boston Bowling Bag – Underarm Shoulder Bag

This underarm bag is built from smooth calfskin leather with a refined satin-matte finish, available in black or dark espresso brown. Continuous wrap-around leather straps form-fit down the front and back panels, reinforcing the bag's slouchy yet tailored box shape.

Calfskin underarm bag with an elongated strap drop

Dual ultra-slim flat straps are cut with an elongated drop to sit comfortably under the arm rather than on the shoulder. A full-length top zipper with a polished silver-toned slider closes the whole opening in one smooth pull, while the interior stays organized with a central partition, a side zip pocket, and a slip divider.
