The Standard and Premium Daypacks are just that, a standard daypack and a premium daypack. Zippered closure, rounded top, gusseted pocket on the back, a grab handle and padded shoulder straps come together at the top with a ring. A divider is set inside with pockets. Either could work well as a briefcase to wear on the back, and they both would work great at school. Because they’re made of waxed canvas, they’re water resistant and tough as tin…Hence the name tincloth. The premium has more leather: the bottom, trim on the pocket and across the top, and has a great grab handle. If you are wavering between a daypack and a briefcase, these packs deserve consideration.
