This thing goes way back. The style was originally used by stonemasons to haul their tools to construction sites — and we figured a mason bag could work wonders for modern times, too. It’s built from thick, capable canvas, with a heavy-duty, reinforced frame. The interior pocket offers enough space to stash a laptop, safely suspending it above the bottom of the bag. The handles and buckles are cut from handsome leather, and a seatbelt-style nylon webbing shoulder strap clips onto reinforced, metal D-rings for secure transport.
