Hydronote All-Weather Notebooks:
Hydronote All-Weather notebooks are made with military-grade polyester covers from TerraSlate and contain 100% water-resistant and rip-resistant interior sheets of Hydronote paper. The sheets are 54# and are 150 GSM.
Hydronote can be written on with any type of pen, pencil, crayon, or marker. For ultimate durability and longevity, we recommend ballpoint pens or Sharpie pens. Unlike Wire-O binding that will crush and bend, Hydronote All-Weather Notebooks use a single-strand of military-tough, monofilament coils that won't crush, scratch, change color, or get bent out of shape.
Take your Hydronote All-Weather notebook anytime you head outdoors and never worry about a drained battery, poor WiFi, or eye strain from too much screen time. Hydronote paper easily repels grease, dirt, water, sweat, salt water, and outdoor sissies.


Additional Notes!
How is Hydronote different than Rite in the Rain?
Hydronote looks, feels, writes, and acts just like paper - but with the addition of it being water-resistant and rip-resistant, whereas Rite in the Rain often requires a special pen as it has a wax-like coating that feels unnatural and can smudge easily.
Hydronote pages are water-resistant like Rite in the Rain, but are also rip-resistant which is important in any outdoor or field application. Your notes wouldn't be very useful if your pages tore out!
What's the difference between Hydronote and TerraSlate?
TerraSlate is the original, military-grade polyester substrate, that is incredibly durable and can be submerged indefinitely. While it would make an incredible notebook, it is somewhat cost-prohibitive. TerraSlate is compatible with ballpoint pens, markers, laser printers, and copy machines.
Hydronote looks and feels just like regular paper but has a thin film on the inside that allows it to be water-resistant and rip-resistant.
