01 / Materials
Quilt & Microfiber
Matte microfiber PU with a leather-look hand, quilted over light padding — sculptural waves on the Wave, racing stripes on the Arc — with smooth leather-look panels and a reinforced base band. Materials are named honestly on every product.
02 / Hardware
Gold-Tone Zinc
Polished zinc-alloy hardware with anti-tarnish plating: the oversized charm ring, the Arc's sweeping zip, a padlock charm. No borrowed logos, ever. The PORTELLE name is engraved once per bag — on the smooth leather hangtag that hangs from the ring.
03 / Construction
The Campus Layout
Inside, the layout is the invention: laptop and tablet ride in a padded bay along the back wall, opposite the books. A bottle holder sits at one end, small pockets take the charger and earbuds, an external pocket swallows a 40 oz tumbler — and hidden straps convert the tote to a backpack.
