The Ristretto is a lightweight vertical messenger bag with a built-in padded compartment that cradles your laptop from all sides: top, front, back, and bottom. Seven pockets (not including the main compartment) provide places to organize your pens, power supply, cables, portable mouse, cell phone, iPod, magazines or files.
The X300 is less than 0.73” at its thinnest and starts out at 2.93 lb: the Ristretto is the bag to carry the X300 and its accessories and yours, but not too much else. Available in colors: Olive/Cayenne, Black/Olive, Plum/Wasabi, Steel/Sapphire, and Black/Steel.
The Ristretto. $70. Available for pre-order, ships mid-April.
