How many zip-top bags have you thrown out in your camping career? For me, the answer is "a lot."
But from now on, my guidebooks, maps, and other knickknacks wont go in plastic bags, but into Pacific Outdoor Equipment's fabric zip-top sacks. They come in the four most common zip top bag sizes, including quart and gallon, and are just as light. They're made of cloth, with a window for easy viewing of contents.
So long, Ziploc.
