The 4.625" x 7” side spiral notebook is fully prepared for any challenge mother nature throws at it. This book comes in a compact but comfortable size for taking plenty of notes, and our Rite in the Rain all-weather paper can handle any weather encounter in the field. Impact resistant wire-o binding won't lose its shape when tossed around in packs or put in a back pocket, and the polydura cover defends your notes from scratches and stains. The entire notebook is recyclable using most curbside programs; simply separate the wire-o binding from the cover prior to recycling for easier processing. Each notebook contains 64 pages/32 sheets.
