We love the scenester pocket notebooks from Field Notes. Durable, rugged, hip, and made in the U.S.A. Each booklet is 48 pages.
Field Notes has a special edition called The National Crop. These packs of six notebooks celebrate farmers and the six leading crops they grow: corn, soybeans, hay, wheat, cotton, and sorghum. Each notebook is "chock full of information about them." Each set includes a map and a logo patch to put on your denim jacket, bike bag, or overalls.
Another edition by Field Notes is the American Tradesman which includes a 7 inch pencil, instructions for sharpening, and graph paper.
