Patagonia Yerba - Black

This 2015 Yerba has been revised and offers just a bit more volume than before: 24 liters instead of 22.  It's a single-compartment, streamlined top loader that provides easy zip access to the main compartment so you can get to your gear quickly.

The Yerba is a cleanly designed 24 liter daypack that has the room & features to hold a day's worth of goods when you hit the trail, bike path or subway. It's single compartment accommodates reading materials, lunch and a jacket; inside, a raised, padded sleeve with buckle closure holds most 15-inch laptops.

For day hikes, leave the laptop at home and slip a hydration reservoir in the computer sleeve (which comes with a tube port).
