Tom Bihn would be my recommendation. You can select the colors and materials. I personally like the Synapse, but they have other models too. Their packs are designed for organization and easy access. Can be used in an office setting or for all types of traveling and commuting. And the pack reduces in size when not full.
Comes in a variety of colors and fabrics
