Remember that tear proof, water resistant material that everything from coveralls to mailing envelopes is made from? That which shall not be named specifically? Well - we call it Duratek, and it's lightweight, tear resistant, water resistant, and generally pretty awesome. The All Day Tote is made for the long haul, but it works for the short haul... or the medium haul. Whether you're bringing home the groceries or taking some work home with you, or toting a change of clothes, this bag has the room you need.
