Fold-over flap has magnets to keep closed.

Alternate pocket for tablet would be just under the flap as it is approx. 10" x 7" in size.

Then you go into the interior of the bag and there are several other pockets, some with zippers some without.

A smaller laptop would fit but my extra large laptop will not fit.

See the label in the pictures for the dimensions of the bag as provided by Crate & Barrel.

The color is gray and it looks like a greenish-gray to me.

It is a super soft leather.
