The Grams28 151 Stealth Backpack is a professional Italian leather backpack designed for those who want an elegant, spacious, and perfectly organized accessory. Created to accompany work, travel, commuting, and photography, it combines a sleek, contemporary aesthetic with a technical structure, designed to protect laptops, devices, accessories, and creative tools.
Made from hammered Italian cowhide leather, it offers a refined and timeless presence, ideal for those seeking a premium, functional, and distinctive business backpack.
The Grams28 151 Stealth Backpack is designed to offer the perfect balance between elegance and functionality. The hammered Italian leather gives the backpack a premium, discreet, and professional look, making it suitable for both business environments and daily commutes.
The V2 version improves comfort and internal organization. The main compartment features freely configurable dividers, designed to adapt to various needs: laptops, cameras, lenses, tech accessories, documents, pouches, and personal items can be organized neatly and securely.
The separate and padded laptop compartment allows you to carry a computer up to 16", keeping it protected and separate from the rest of the contents. Internal pockets help manage cables, chargers, small devices, and daily accessories, while microfiber pockets with zippers are ideal for more delicate items.
The rear pass-through allows the backpack to be attached to a luggage trolley, making it particularly suitable for business trips. The updated, padded, and breathable shoulder straps and back panel enhance comfort even during prolonged use.
Veining, grain variations, and any small marks on the surface are natural characteristics of genuine leather and make each product unique.
Configurable dividers are padded panels that are removable and repositionable inside the main compartment. They can be moved freely to create compartments of different sizes depending on the content: one configuration for a laptop + camera + lenses, another for a laptop + documents + tech accessories, and another for daily use without a camera. This flexibility makes the Stealth Backpack suitable for many different contexts without having to switch backpacks.
Yes. Thanks to the configurable dividers and padded structure on all sides, the Stealth Backpack is compatible with mirrorless cameras like the Sony A7C and its lenses. The dividers allow you to create custom compartments for camera bodies and optics, protecting them during transit. The microfiber pockets with zippers are ideal for filters, memory cards, and delicate accessories.
The Stealth Backpack has a separate and padded laptop compartment, compatible with laptops up to 16", including the MacBook Pro 16". The compartment is physically separate from the main compartment, so the laptop never comes into contact with cameras, lenses, or other items.
The internal microfiber-lined pockets with zippers are designed for delicate items that should not get scratched: glasses, camera screens, photographic filters, memory cards, watches, or any accessory with sensitive surfaces. Microfiber is a soft material that does not leave marks and protects against light impacts.
The V2 version has updated shoulder straps and back panel: both are padded and breathable, designed to distribute weight evenly and reduce sweating during prolonged use. With a 21-liter capacity and an empty weight of 1,950g, it is a backpack designed to be carried comfortably all day long.
Yes. The rear pass-through allows the backpack to be secured to the telescopic handle of a luggage trolley, making it very practical during business trips at the airport or train station. This is a fundamental feature for those who frequently travel with carry-on luggage.
Yes. The Stealth Backpack is made from hammered Italian cowhide leather, sourced from the Gruppo Mastrotto tannery in Adria. The hammered finish makes the surface more resistant to scratches and wear than smooth leather, maintaining an elegant and professional appearance over time. The tanning process is environmentally certified.
Both are hammered cowhide leather backpacks from Gruppo Mastrotto, but with different purposes: the 151 Stealth Backpack V2 is larger (21 L vs. 13.5 L), has configurable dividers for photography and tech, a padded structure on all sides, and microfiber pockets — it is the backpack for those who carry a lot and need advanced protection and organization. The 150 Daypack is more compact and lighter, ideal for those carrying a laptop, tablet, and daily accessories with a more essential profile.
For ordinary cleaning, a soft, dry cloth is sufficient. To maintain the softness and shine of the leather over time, it is recommended to periodically apply a neutral leather conditioner. Avoid prolonged exposure to heavy rain, direct sun, and excessive heat. In case of accidental wetting, blot gently and allow to air dry away from heat sources.
Yes, it is a valuable gift for anyone who works daily with a laptop and camera and appreciates genuine Italian leather accessories. The combination of advanced functionality, premium materials, and professional design makes it a cherished gift for important birthdays, graduations, anniversaries, and any special occasion.
