GUIDI's Q100 is a study in restraint. Where the Pescia tannery is known for boots and heavy leather goods built to outlast decades, this belt bag strips the philosophy to its essential gesture -- soft horse full grain leather, piece-dyed after construction, shaped into a crescent that holds only what matters. The green is rare in GUIDI's vocabulary. Most of their work lives in black. This colorway arrived through the same object-dyeing process the family has used since 1896: the finished bag submerged whole, the pigment settling deeper into seams and edges, lighter where the nap stands open.

The leather exterior is turned rough-side-out, exposing the napped grain of the horse hide. Run your hand across it and the texture shifts direction -- darker one way, paler the other, the fibers catching light like moss on stone. It is unlined, as GUIDI intended. Nothing between you and the hide. The bison strap adjusts to sit at the waist or cross the chest, and the single diagonal zip keeps the interior secure without ceremony.
