Is the Montsouris GM good for everyday use?

Yes, if you carry a lot. The GM is the large size, with a main drawstring compartment, a front zip pocket and an interior patch pocket. It is roomier than most designer backpacks but bulkier to wear all day.

How does it compare with the smaller Montsouris PM?

The PM is the compact version; the GM carries more, including a laptop and a change of clothes for a night away. The GM is heavier and more noticeable on the back, so choose it only if you need the space.

Is the drawstring closure secure?

It is a leather drawstring with a magnetic snap over the top. That is quicker to open than a zip but less enclosed, so keep valuables in the front zip pocket or the interior patch pocket in crowds.

What is the Monogram canvas and Empreinte leather combination?

The body is Louis Vuitton's coated Monogram canvas, with black Empreinte leather trim, top handle and straps. The canvas resists light rain, but the leather trim and drawstring need protection in heavy weather.

What fits inside the GM?

At roughly 10.5 by 9 by 5.75 inches, it holds a tablet or small laptop, a water bottle, a pouch and a light layer. The single main compartment means you will want small organizers.

Is it a good travel backpack?

It works as a personal item or day bag, with a top handle for carrying by hand and adjustable straps for the back. The drawstring top and leather trim make it less weatherproof than a technical travel pack.
