Manhattan Portage Webb 15-inch Convertible Briefcase

The Manhattan Portage Webb is a convertible laptop briefcase built for 15-inch devices. It uses 1000D CORDURA® Classic fabric with tarpaulin vinyl accents and a magnetic flap closure. Reversed YKK® zippers add extra water resistance. The bag carries as a briefcase or cross-body with a removable shoulder strap that includes a rubberised pad. Three large open pockets sit under the closure flap and an open back-panel pocket provides quick access.

Who this suits and who should look elsewhere

Commuters who want a single bag that switches between briefcase and messenger styles will appreciate the dual-carry design. Side zippers expand capacity when extra gear is needed. 3M™ reflective tape accents improve visibility in low light. Buyers who need a dedicated padded laptop sleeve, internal organisation panels or a larger device compartment should look elsewhere.

Capacity and headroom

The main compartment fits a 15-inch laptop plus daily essentials, and side zippers open to increase volume for bulkier loads. Three open pockets under the flap hold items you reach for often, while the back-panel pocket keeps a phone or transit card handy. The magnetic flap and reversed YKK® zippers resist light rain, but the bag is not rated for heavy downpours or submersion.

Questions about this item

What laptop size fits in the 15-inch compartment?

The briefcase is built for laptops up to 15 inches, so a 15-inch device fits in the main compartment.

Does the removable shoulder strap work with the original 1983 Manhattan Portage mounting points?

The bag uses current D-ring attachments; the strap clips onto those rings and is not compatible with vintage 1983 hardware.

How can I confirm the reversed YKK zipper is sealing correctly after I pack the bag?

Close the zipper fully and run a finger along the teeth — you should feel a smooth, continuous seal with no gaps.
