The ultimate cup of coffee starts with this hemp fabric coffee filter.  Use them over and over, use them camping, use them travelling, just use them.  I rocemmend rinsing out daily, and throwing in the wash weekly.  Though use a detergent without scent and additives as you dont want your coffee tasting like Tide.  I actually just boil mine once a week to remove the oil and coffee build up.  We make these in our Oregon studio.
