The built-in interior padded compartment, located in the main compartment of the Ristretto, protects your MacBook Air and 13" MacBook Pro inside of the bag. The padded compartment is made with .25" (6mm) open-cell foam laminated with durable 4 Ply Taslan® on the outside, and features an interior of super-soft brushed tricot. The back side of the Ristretto is padded with 1/4" closed cell foam.

The main, open-top compartment and front zippered pocket of the Ristretto are covered by an asymmetrical flap that closes with the distinctive TOM BIHN off-set buckle.

Under the flap, you'll find a curved, #8 YKK Uretek® splash-proof zipper which secures the front pouch of the Ristretto. Inside this front pouch is an organizer with pockets for pen, iPhone and passport or wallet. There's also plenty of room inside this pouch for power supply, phone charger, sunglasses.

This front pouch has one o-ring. The main compartment of the Ristretto features three o-rings. Attached to one o-ring is an 8" Key Strap. (Additional and extended length Key Straps can be purchased separately.) The Key Strap is useful for keeping track of your keys (many folks leave their keys attached to the key strap.) It can also be used to clip a pocket watch or Swiss Army knife to the bag. One can also clip a Guardian Light, Clear Organizer Wallet, or Clear, Padded, Cordura, or Cork Organizer Pouches to the interior o-rings.

The back of the Ristretto has a slanted, open-top pocket ideal for storing papers, a magazine or a newspaper. An easy-to-grab handle on the top/back is padded with Poron® foam. Included with the Ristretto is a removable waist strap - great for use if you ride your bike while wearing the Ristretto (motor bike or push bike). The waist strap attaches to two of four available points on the back of the Ristretto: you can attach the strap so that one end is high and the other low, or both high or both low, whatever is comfortable. If you don't plan to use the waist strap, it is easily removable and leaves no hardware behind.

You can choose between two different shoulder straps to use with the Ristretto. The Standard Shoulder Strap, included in the price of the Ristretto, is a 1-1/2" wide heavy nylon webbing strap and features a comfortable, wide foam pad that won't slip off your shoulder and is designed to conform to your shoulder and back. For an extra $20.00, you can switch out the Standard Strap for the Absolute Shoulder Strap.

Most people will be satisfied with just one kind of shoulder strap, but, should you choose to do so, you can purchase more than one kind of shoulder strap and switch between them.

The Ristretto is a vertical messenger bag designed to carry your 13" MacBook Air/MacBook Pro and a minimum amount of accoutrements (power supply, pen, notebook, wallet, phone, magazine). Great for realizing the dream of a mobile office: work at the coffee house, on the light rail, at the airport or on the plane.
