The Tumi Alpha 3 Expandable briefcase in elegant grey is the quiet yet unmistakable way to make a statement. Clean lines, a confident silhouette, and a strikingly minimalist aesthetic combine timeless classicism with modern business functionality – for an appearance that exudes competence, whether in the office, at a client meeting, or on the way to the next appointment.
Precision in Material and Craftsmanship
As part of the renowned Alpha 3 series, this briefcase represents TUMI’s uncompromising quality philosophy. The durable blend of nylon and polyester combines a premium feel with high everyday practicality – made for intensive use without losing elegance. Fittings and zippers integrate precisely into the design, the grey colour is deliberately understated and adapts effortlessly to both formal and smart looks. The result is a business statement that emphasizes professionalism while remaining pleasantly understated.
Space, Organisation, and Flexibility for Your Day
Measuring approximately 32 x 40.5 x 19 cm with a base volume of about 14 liters, the Alpha 3 offers exactly the organized storage that demanding workflows require: documents and technology find structured space, essentials are intuitively accessible. The expandable design creates additional room when needed – ideal when the day demands more than planned – without upsetting the slim shape. The weight of about 2.44 kg underscores the substantial construction: tangible stability that promises durability and securely supports your equipment.
