Rite in the Rain 673 Durarite Waterproof Side Spiral Notebook (4.625" x 7"), White

Impact-resistant Wire-O doesn’t get bent out of shape when tossed around above or below deck. The Polydura cover creates a tough but flexible outer shell defending your notes from scratches. Even in extreme underwater conditions, what you write won’t rub off these tear-resistant waterproof sheets.
