Rite in the Rain says:
The Tactical Loose Leaf sheets have a round 6-hole punch to fit the Rite in the Rain Field Ring Binders (sold seperately). Printed on 32# Rite in the Rain paper. 100, 4 5/8 in x 7 in sheets per pack of waterproof, weather-proof paper.
The Rite in the Rain Loose Leaf sheets use the same 6 ring binding as so many other organisers and notebooks - so these waterproof pages can be used in your own binder if you have one - or buy them for the Rite in the Rain Field Binder.
