This backpack comes from Noodlehead Patterns, a personal favorite! Functional foremost.... able to hold a laptop within a sleeve.... The vinylize quilter's cotton makes the lining waterproof. The inside zipper pocket has vinyl as well. The outside zipper pocket is large enough to hold a wallet with additional room for pens, pencils, etc. 

The navy backpacks are made from Navy Duck Canvas and Indoor/ Outdoor Upholstery fabric. They too are wipeable with a damp sponge.  

This tote measures: 15"h x 11.5"w X 4"d
